Description

  The present invention relates to a vehicle seat assembly.

  Some vehicle seat assemblies include a side bolster disposed on the side of the seat back of the seat. The side bolster is also called a seat bolster or a side support. The side bolster is interposed between the side surface of the passenger compartment and the side surface of the seat back, and can support the side of the upper half of the occupant seated on the seat. A general side bolster is composed of a bolster base serving as a skeleton and a skin covering the surface of the bolster base. Such a vehicle seat assembly is known, for example, from US Pat.

  In the vehicle seat assembly known from Patent Document 1, the upper body of an occupant seated on a rear seat is supported by a side bolster. The side bolster is adjacent to the outer side surface of the rear seat in the vehicle width direction and attached to the vehicle body.

  In general, the end of the side bolster in the vehicle width direction, that is, the outer end is located in the vicinity of the door opening. The door opening is a doorway that is formed on the side of the vehicle body and is opened and closed by a side door. A rubber seal member (also referred to as a weather strip) is fitted into the peripheral edge of the door opening. The seal member is integrally formed with a blindfold lip having elasticity. The blindfold lip covers the gap in the vehicle width direction between the peripheral edge of the door opening and the outer end of the side bolster so that it cannot be seen.

  In order to improve the appearance of the peripheral edge of the door opening and the periphery thereof, the width of the blindfold lip, that is, the length of the blindfold lip extending from the seal member toward the side bolster is preferably as small as possible. However, there is a limit to reducing the width of the blindfold lip.

  On the other hand, instead of the blindfolding lip, it is conceivable to provide the seal member with a vertically long blindfolding groove opening inward in the vehicle width direction. However, the thickness of the side bolster on the outer side in the vehicle width direction is large. The outer end of the side bolster in the vehicle width direction cannot be directly fitted into the blindfold groove.

  Therefore, it is conceivable to reduce the width of the side bolster in the vehicle width direction and to interpose a garnish (decorative member) between the outer end of the side bolster and the peripheral edge of the door opening. The garnish may be a thin vertical plate member whose plate surface is directed in the vehicle longitudinal direction. The thickness of the outer end in the vehicle width direction of the garnish is smaller than the thickness of the outer end in the vehicle width direction of the side bolster. For this reason, the outer end of the garnish in the vehicle width direction can be easily fitted into the blindfold groove. Since the end is fitted into the blindfold groove portion, it cannot be seen from the outside. The depth of the groove may be small.

  However, as the garnish increases, the number of vehicle parts increases. This increases the cost of the vehicle, so there is room for further improvement.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a vehicle seat assembly technique that can reduce the number of components in order to enhance the appearance of the periphery of the seat and the door opening and the surrounding area.

According to the present invention, a vehicle seat assembly includes a door opening that is provided on a side surface of a vehicle body and that is opened and closed by a side door, a seat provided in a passenger compartment so as to be positioned in the vicinity of the door opening, and the seat A side bolster adjacent to the side of the seat back of the seat so as to be able to support the upper body of the occupant seated in the seat.
The side bolster includes a bolster base serving as a skeleton, and a skin covering the front surface of the bolster base. A garnish is integrally formed on the outer side in the vehicle width direction of the bolster base via a vertical groove that is elongated in the vertical direction. The garnish is a vertical plate-shaped portion with the plate surface facing in the vehicle front-rear direction. An end portion on the outer side in the vehicle width direction of the garnish is positioned along the rear portion of the peripheral portion forming the door opening, and the end fitting vertical groove provided at the rear portion of the peripheral portion forming the door opening It is inserted in. A through hole is formed in the vertical groove portion. A skin latching portion is provided on the back surface of the bolster base. The outer end of the skin in the vehicle width direction is located in the longitudinal groove. The skin includes a locking portion that is latched to the skin latching portion through the through hole.

  Thus, the side bolster is adjacent to the side surface of the seat back, and the appearance is enhanced by covering the front surface of the bolster base. On the other hand, the garnish is a member for preventing the gap between the outer end of the side bolster in the vehicle width direction and the peripheral edge of the door opening from being visible from the outside. For this reason, the garnish can be formed in a vertical plate shape that is elongated vertically and has a plate surface directed in the vehicle front-rear direction. The garnish need not be covered by the epidermis.

  A side bolster whose skin is covered on the front surface of the bolster base and a garnish positioned on the side of the bolster base on the outer side in the vehicle width direction are integrally formed. For this reason, compared with the case where the side bolster and the garnish are separate members, the number of parts can be reduced. And since the edge part of the vehicle width direction outer side of this garnish is engage | inserted by the end part vertical groove part provided in the rear part of the peripheral part which forms a door opening, it cannot be seen from the outside. For this reason, the peripheral part of a door opening and its external appearance property can be improved. As described above, the number of components is small and the assembly to the vehicle body is easy to improve the appearance of the peripheral portion of the seat and the door opening and the surroundings.

  Further, the garnish is integrally formed on the outer side in the vehicle width direction of the bolster base via the vertical groove. The longitudinal groove serves as a boundary between the bolster base and the garnish. The outer end in the vehicle width direction of the skin covering the front surface of the bolster base can be gathered at the position of the longitudinal groove. That is, a skin latching portion is provided on the back surface of the bolster base. The outer end of the skin in the vehicle width direction is positioned in the longitudinal groove, and the latching portion of the skin is passed through the through hole of the longitudinal groove and latched to the skin latching portion. As a result, the outer end of the skin in the vehicle width direction can be attached to the back surface of the bolster base.

  In this way, the side bolster body that covers the front surface of the bolster base can be easily applied to the bolster base even though the side bolster with the skin and the garnish that does not require the skin are integrated. And can be installed with good appearance. Therefore, it is possible to cover the epidermis only on the bolster base with good appearance locally. In addition, the width of the side bolster having the outer skin can be maximized by bringing the longitudinal groove portion serving as the boundary between the bolster base and the garnish to the door opening side as much as possible.

  Preferably, the skin includes a trim member that can be fitted into the longitudinal groove. The trim member is a member that is fitted into the longitudinal groove portion so that the tension state of the skin with respect to the front surface of the bolster base is made uniform when the locking portion is latched to the skin latching portion. For this reason, it is possible to evenly stretch the epidermis to the front surface of the bolster base as much as possible without causing wrinkles or slack. Therefore, the appearance of the side bolster can be further improved.

  In the present invention, a garnish for shielding the terminal portion between the outer end of the side bolster in the vehicle width direction and the peripheral edge of the door opening is integrated with the side bolster. For this reason, in order to improve the external appearance of the periphery of the seat and the door opening and the periphery thereof, it is possible to make the structure easy to assemble to the vehicle body with a small number of parts. Moreover, the appearance of the side bolster can be enhanced by maximizing the width of the side bolster having the skin by appropriately setting the position of the longitudinal groove portion that becomes the boundary between the bolster base and the garnish. .

It is formed symmetrically.

  The vehicle 10 is a so-called four-door vehicle in which a vehicle body 11 includes left and right front doors 12 and left and right rear doors 13. The left and right side surfaces of the vehicle body 11 have left and right door openings 14 located on the front side and left and right door openings 15 located on the rear side. Hereinafter, the left and right door openings 14 positioned on the front side will be referred to as “left and right front door openings 14” as appropriate. Further, the left and right door openings 15 positioned on the rear side are referred to as “left and right rear door openings 15” as appropriate.

  The left and right front door openings 14 are opened and closed by the left and right front doors 12. The left and right rear door openings 15 are opened and closed by the left and right rear doors 13. The left and right front doors 12 and the left and right rear doors 13 are side doors that are substantially vertical when the door openings 14 and 15 are closed, and are attached to the vehicle body 11 by hinges (not shown) so as to be opened and closed. .

  A peripheral edge portion 21 forming the left and right front door openings 14 in the vehicle body 11 is composed of left and right front pillars 22, left and right center pillars 23, left and right side sills 24, and left and right roof rails (not shown). Yes. The left and right peripheral edge portions 25 forming the left and right rear door openings 15 in the vehicle body 11 are constituted by left and right center pillars 23, left and right rear pillars 26, left and right side sills 24, and left and right roof rails (not shown). Has been. That is, the left and right peripheral edge portions 21 and 25 are formed in a loop shape when the vehicle 10 is viewed from the side.

  As shown in FIGS. 2 and 3, the left and right peripheral edge portions 25 forming the left and right rear door openings 15 in the vehicle body 11 are overlapped with the edge of the outer panel 27 of the vehicle body 11 and the edge of the inner panel 28. And a joined flange. The left and right peripheral edge portions 25 forming the left and right rear door openings 15 are appropriately referred to as “left and right flanges 25”. The left and right rear pillars 26 include an outer panel 27 and an inner panel 28.

  The left and right peripheral edge portions 25 are provided with left and right sealing members 30 (also referred to as weather strips 30) made of an elastic material such as rubber over the entire circumference of the left and right peripheral edge portions 25. The left and right seal members 30 are hereinafter referred to as “left and right inner seal members 30”. The left and right inner seal members 30 are formed in a loop shape when the vehicle 10 is viewed from the side.

  Hereinafter, the left inner seal member 30 will be described in detail. The right inner seal member 30 has the same configuration as that of the left inner seal member 30 except that it is bilaterally symmetric.

  As shown in FIG. 4, the left inner seal member 30 is formed integrally with the welt part 31 (mounting part 31) fitted to the peripheral part 25 over the entire periphery and the weld part 31 over the entire periphery. It comprises a seal portion 32 and a blindfold lip 33 formed integrally with a part of the welt portion 31.

  The welt portion 31 is formed in a substantially U-shaped cross section that opens toward the peripheral edge 25, and is fitted into the peripheral edge 25. As a result, the inner seal member 30 is fitted to the peripheral edge portion 25 over the entire circumference.

  The seal portion 32 is formed in a hollow cross section, and is interposed between the inner surface 13a of the left and right rear doors 13 and the peripheral edge portion 25 when the left and right rear doors 13 are closed. As a result, the left and right rear door openings 15 are sealed by the inner seal member 30.

  The blind lip 33 is formed in a substantially L-shaped cross section that is continuous with the bottom 31 a of the U-shaped welt portion 31, and is located only at the rear portion of the peripheral edge 25 of the left and right rear door openings 15. . Here, the “rear part of the peripheral part 25” refers to a rear part of the peripheral part 25 in a loop shape when the vehicle 10 is viewed from the side.

  More specifically, the blindfold lip 33 includes a leg 34 extending from the bottom 31 a of the welt 31 to the front of the vehicle and a lip 35 extending from the tip of the leg 34 into the vehicle compartment 16. Thus, the blind lip 33 is provided at the rear portion of the peripheral edge portion 25 that forms the left rear door opening 15.

  The leg 34 is located at the approximate center of the bottom 31 a of the welt 31 in the vehicle width direction. For this reason, the base end 35 a of the lip portion 35 is located at the approximate center in the vehicle width direction of the bottom portion 31 a of the welt portion 31. The straight line Ls in the longitudinal direction of the vehicle body passing through the center in the vehicle width direction of the welt part 31 is referred to as a welding part tangent Ls. The base end 35a of the lip portion 35 is located on or near the welt portion tangent Ls. The width Wr of the blindfold lip 33 in the vehicle width direction is the length from the proximal end 35a to the distal end 35b of the lip portion 35.

  The lip portion 35 is separated from the bottom 31a of the welt portion 31 toward the front of the vehicle. For this reason, an elongated groove 36 is formed between the bottom 31 a and the lip 35 so as to open in the up-down direction toward the interior of the passenger compartment 16. The groove portion 36 is surrounded by the bottom portion 31 a of the welt portion 31, the leg portion 34, and the lip portion 35. Thus, the groove 36 is located on the back surface of the blindfold lip 33.

  As shown in FIG. 3, left and right outer seal members 39 are provided on the inner surfaces of the peripheral portions of the left and right rear doors 13. The left and right outer seal members 39 are located on the outer side in the vehicle width direction with respect to the left and right inner seal members 30. In this way, the left and right rear doors 13 are double sealed when closed.

  As shown in FIG. 1, a front seat 41, 42 (a driver seat 41 and a passenger seat 42) and a rear seat 43 are provided in the compartment 16 of the vehicle 10. The rear seat 43 is, for example, a three-seater rear seat, and is positioned in the vicinity of the left and right rear door openings 15. The rear seat 43 includes a seat cushion 44 and a seat back 45.

  The seat back 45 can be tilted up and down with respect to the seat cushion 44. The seat back 45 is constituted by a single seat back member or a seat back member divided into left and right parts. When the seat back 45 is constituted by a seat back member divided into left and right parts, the respective seat back members can be raised and lowered individually.

  As shown in FIGS. 1 and 2, the vehicle 10 includes a vehicle seat assembly 50. The vehicle seat assembly 50 includes the left and right rear door openings 15, left and right inner seal members 30, a rear seat 43, and left and right side bolsters 60 and 60.

  The left and right side bolsters 60, 60 are also called seat bolsters or side supports. The left and right side bolsters 60 and 60 are adjacent to the side surface of the seat back 45 of the rear seat 43 so as to support the side of the upper body of the occupant seated on the rear seat 43. That is, the left and right side bolsters 60, 60 are interposed between the left and right side surfaces 11 a of the vehicle body 11 that form the passenger compartment 16 and the left and right side surfaces 45 a, 45 a of the seat back 45. Between the left and right side surfaces 45a and 45a of the seat back 45 and the left and right side bolsters 60 and 60, there is a gap at least enough to allow the seat back 45 to rise and fall.

  Hereinafter, the left side bolster 60 will be described in detail. The right side bolster 60 has the same configuration as that of the left side bolster 60 except that it is bilaterally symmetric.

  As shown in FIGS. 2 and 3, the left side bolster 60 includes a bolster base 61 serving as a skeleton, a cushion body 62 that covers the front surface 61 a of the bolster base 61, and the bolster base from above the cushion body 62. And an outer skin 63 that covers the front surface 61a of 61. The presence or absence of the cushion body 62 is arbitrary. For this reason, the skin 63 includes a structure that directly covers the front surface 61 a of the bolster base 61.

  The bolster base 61 is a vertically elongated member that extends from the lower end to the upper end of the seat back 45 of the rear seat 43 along the side surface 45a outside the seat back 45 in the vehicle width direction. Is formed.

  More specifically, the front surface 61a of the bolster base 61 is inclined from the side surface 45a on the outer side in the vehicle width direction of the seat back 45 so as to go forward in the vehicle width direction. The size of the bolster base 61 is set to a size that can sufficiently support the side of the upper body of the occupant.

  The cushion body 62 is made of a material equivalent to the cushion body of the seat back 45, for example, a urethane foam material. The skin 63 is made of the same material as the skin of the seat back 45. For this reason, the left side bolster 60 can obtain a touch (including visibility, touch, and texture) equivalent to that of the seat back 45. The cushion body 62 may be joined or integrally formed on the back surface of the skin 63.

  As shown in FIG. 5, a locking claw 71 is formed at the upper end of the bolster base 61. A leg portion 72 is formed at the lower end of the bolster base 61. The locking claw 71 is latched to the hanging portion 73 of the vehicle body 11, and the leg portion 72 is fixed to the vehicle body 11 by a bolt 74, whereby the left side bolster 60 is fixed to the vehicle body 11. For this reason, even when the seat back 45 shown in FIG. 2 falls forward, the left side bolster 60 maintains an upright posture.

  As shown in FIG. 3, a garnish 90 is integrally formed on a side portion 61 b of the bolster base 61 on the outer side in the vehicle width direction through a vertical groove portion 80 elongated in the vertical direction. That is, the vertical groove portion 80 is formed integrally with the side portion 61 b of the bolster base 61 on the outer side in the vehicle width direction. The garnish 90 is formed integrally with a side portion 80a of the longitudinal groove portion 80 on the outer side in the vehicle width direction.

  As shown in FIG. 4, the longitudinal groove 80 is formed in a substantially U-shaped cross section that opens toward the front of the vehicle. More specifically, the vertical groove portion 80 includes a vertical plate-like first wall 81 extending rearward from the side portion 61b of the bolster base 61 in the vehicle width direction and a rear end of the first wall 81 in the vehicle width direction. A vertical plate-like bottom plate 82 extending outward, and a vertical plate-like second wall 83 extending forward from the end of the bottom plate 82 in the vehicle width direction.

  The longitudinal groove portion 80 is formed with a vertically elongated groove 84 surrounded by the first wall 81, the bottom plate 82, and the second wall 83. The vertical groove portion 80 is formed with at least one through hole 85 (for example, a plurality of through holes 85 in the longitudinal direction of the vertical groove portion 80). The through hole 85 penetrates the bottom plate 82 in the vehicle front-rear direction and is preferably adjacent to the second wall 83.

  As shown in FIGS. 2, 3, and 6, the garnish 90 (decorative member 90, cover member 90) includes a side 61 b on the outer side in the vehicle width direction of the bolster base 61 and the left rear door opening 15. It is a vertically elongated member capable of closing a space between the rear portion of the peripheral portion 25 to be formed (the rear portion of the loop-shaped peripheral portion 25 when the vehicle 10 is viewed from the side).

  As shown in FIG. 3, an end 91 on the outer side in the vehicle width direction of the garnish 90 is a rear portion of the peripheral portion 25 that forms the left rear door opening 15 (when the vehicle 10 is viewed from the side, a loop shape). It is located along the rear portion of the peripheral edge 25. The garnish 90 is generally along the extension of the front surface 61 a of the bolster base 61.

  Further, an end 91 on the outer side in the vehicle width direction of the garnish 90 is fitted in the groove 36 of the inner seal member 30. In this manner, the groove 36 of the inner seal member 30 is elongated in the vertical direction so that the end 91 can be fitted. The groove 36 of the inner seal member 30 is hereinafter referred to as “the end fitting vertical groove 36”.

  The lip portion 35 of the blindfolding lip 33 constituting the end fitting vertical groove portion 36 is positioned immediately before the end portion 91 of the garnish 90 on the outer side in the vehicle width direction. As a result, the blindfold lip 33 having a substantially L-shaped cross section has a gap in the vehicle width direction between the end portion 91 and the end portion 91 and the peripheral edge portion 25 of the left rear door opening 15. It is covered so that it cannot be seen. Therefore, the appearance of the left rear door opening 15 and its surroundings can be enhanced.

  Moreover, as shown in FIG. 4, the width Wr of the blindfold lip 33 in the vehicle width direction is as small as possible so as to cover the end 91 from the left rear door opening 15 side. Accordingly, it is possible to further improve the appearance of the blindfold lip 33 itself, the left rear door opening 15 and its surroundings. Since the garnish 90 only covers the gap in the vehicle width direction between the inner seal member 30 and the bolster base body 61, the garnish 90 is small and less conspicuous. For this reason, the garnish 90 plays the role of the edge of the peripheral edge 25 of the left rear door opening 15, that is, a decorative member.

  As described above, the end 91 of the garnish 90 on the outer side in the vehicle width direction is fitted into the end fitting vertical groove 36. Therefore, the width Wr of the blindfold lip 33 in the vehicle width direction does not need to be larger than the depth of the end fitting vertical groove 36. The blindfold lip 33 can be further reduced in size.

  As shown in FIG. 7, a plurality of skin latching portions 76 (hooks 76) are provided on the back surface 61 c of the bolster base 61. The plurality of skin latching portions 76 are formed in a substantially L shape or a substantially J shape, and are located in the vicinity of the periphery in the back surface 61 c of the bolster base 61.

  As shown in FIGS. 3, 7, and 8, the outer end of the outer skin 63 in the vehicle width direction is located in the vertical groove 80 and is fitted into the vertical groove 80. The skin 63 includes a plurality of extension portions 101, a plurality of locking portions 102, and one trim member 103.

  The plurality of extending portions 101 extend outward from the peripheral edge 63 a of the skin 63. For example, the plurality of extending portions 101 are band-like portions configured by extending a part of the peripheral edge 63a of the skin 63 outward.

  The plurality of locking portions 102 are members that are provided at the distal ends of the extension portions 101 and are individually latched by the plurality of skin latching portions 76. For example, the plurality of locking portions 102 are formed in an annular shape by folding the distal ends of the extension portions 101 to the back surface side and joining them by stitching or the like.

  Here, among the plurality of extension portions 101, one extending from the skin 63 through the through hole 85 toward the back surface 61c of the bolster base 61 is particularly referred to as a “through-side extension portion 101A”. Among the plurality of locking portions 102, the one provided in the through-side extension portion 101A is particularly referred to as a “through-side locking portion 102A”. Of the plurality of skin latching portions 76, the one on which the penetrating side latching portion 102 </ b> A is latched is particularly referred to as a “penetrating side skin latching portion 76 </ b> A”.

  As described above, the skin 63 includes the locking portion 102 </ b> A that can be hooked on the skin hooking portion 76 </ b> A through the through hole 85.

  The trim member 103 can be fitted into the longitudinal groove portion 80 so that the tension state of the skin 63 with respect to the front surface 61a of the bolster base 61 is made uniform when the plurality of locking portions 102 are latched to the skin latching portion 76. This is also a trim cord. More specifically, the trim member 103 is a vertically elongated member provided at the outer end of the skin 63 in the vehicle width direction, and is constituted by a hard or soft tube.

  As shown in FIGS. 4 and 8, a joining piece 104 is formed integrally with the trim member 103. The trim piece 103 is fixed to the skin 63 by overlapping the joining piece 104 on the outer end of the skin 63 in the vehicle width direction and joining them by sewing or the like. The joining piece 104 may be constituted by a member different from the trim member 103. In that case, the joining piece 104 is joined to the skin 63 while covering the trim member 103.

  The diameter of the trim member 103 is set to be larger than the width of the through hole 85 and smaller than the width of the groove 84 of the vertical groove portion 80. The width of the groove 84 of the longitudinal groove 80 is set to a size that allows both the end of the cushion body 62 on the outer side in the vehicle width direction and the end of the outer skin 63 on the outer side in the vehicle width direction to be fitted.

  As shown in FIGS. 3 and 7, the skin 63 having such a configuration is put on the front surface 61 a of the bolster base 61, and the plurality of locking portions 102 are individually latched on the plurality of skin latching portions 76. To be attached to the bolster base 61.

  In this case, first, of the plurality of locking portions 102, the one on the seat back 45 side is hooked on the plurality of skin latching portions 76. Next, the outer end of the skin 63 in the vehicle width direction is fitted into the groove 84 of the longitudinal groove 80. Next, the penetrating-side extension portion 101 </ b> A and the penetrating-side locking portion 102 </ b> A are passed through the through-hole 85. Next, the penetrating extension 101 </ b> A is strongly pulled toward the back surface 61 c of the bolster base 61. At this time, the trim member 103 contacts the bottom plate 82 of the longitudinal groove 80. As a result, the tension state of the skin 63 with respect to the front surface 61a of the bolster base 61 can be made uniform. Next, the penetrating side locking portion 102A is hooked to the penetrating side skin latching portion 76A. By doing in this way, the skin 63 can be stretched as uniformly as possible with respect to the front surface 61a of the bolster base 61 so as not to be wrinkled or loosened. Accordingly, the appearance of the side bolster 60 can be further improved.

  The above description is summarized as follows. As shown in FIG. 3, the side bolster 60 is adjacent to the side surface 45 a of the seat back 45, and the appearance is enhanced by covering the front surface 61 a of the bolster base 61 with the skin 63. On the other hand, the garnish 90 is a member for preventing the gap between the outer end of the side bolster 60 in the vehicle width direction and the peripheral edge 25 of the door opening 15 from being visible from the outside. For this reason, the garnish 90 can be formed in a vertical plate shape that is elongated vertically and whose plate surface is directed in the vehicle front-rear direction. The garnish 90 need not be covered by the epidermis.

  A side bolster 60 that covers the front surface 61a of the bolster base 61 with a skin 63 and a garnish 90 located on the side 61b on the outer side in the vehicle width direction of the bolster base 61 are integrally formed. For this reason, the number of parts can be reduced as compared with the case where the side bolster 60 and the garnish 90 are separate members. In addition, the end 91 of the garnish 90 on the outer side in the vehicle width direction is fitted into the end fitting vertical groove 36 provided at the rear of the peripheral edge 25 forming the door opening 15, so that it cannot be seen from the outside. For this reason, the peripheral part 25 of the door opening 15 and its external appearance property can be improved. As described above, the number of parts is reduced and the assembly to the vehicle body 11 is easy to improve the appearance of the rear seat 43 and the peripheral edge 25 of the door opening 15 and the surrounding area.

  Furthermore, the garnish 90 is formed integrally with the side portion 61 b of the bolster base 61 on the outer side in the vehicle width direction through the longitudinal groove portion 80. The longitudinal groove 80 is a boundary between the bolster base 61 and the garnish 90. The outer end in the vehicle width direction of the skin 63 that covers the front surface 61 a of the bolster base 61 can be gathered at the position of the longitudinal groove 80. That is, a “penetration-side skin latching portion 76 </ b> A” is provided on the back surface 61 c of the bolster base 61. The outer end of the skin 63 in the vehicle width direction is positioned in the longitudinal groove 80, and the “penetration-side locking portion 102 </ b> A” of the skin 63 is passed through the through-hole 85 of the longitudinal groove 80, Part 76A ". As a result, the outer end of the skin 63 in the vehicle width direction can be attached to the back surface 61 c of the bolster base 61.

  As described above, the side bolster 60 having the skin 63 and the garnish 90 that does not require the skin are integrated, but the outer edge of the skin 63 in the vehicle width direction that covers the front surface 61a of the bolster base 61 is integrated. Can be easily and nicely attached to the bolster base 61. Therefore, it is possible to cover the skin 63 only on the bolster base 61 with good appearance locally. In addition, the width of the side bolster 60 having the skin 63 can be maximized by bringing the longitudinal groove portion serving as the boundary between the bolster base 61 and the garnish 90 toward the door opening 15 as much as possible.

  The vehicle seat assembly 50 of the present invention is suitable for use around a rear seat of a passenger car.
