Description

  The present invention relates to a vehicle seat.

  2. Description of the Related Art Conventionally, for example, a configuration of Patent Document 1 described below is known as a vehicle seat mounted on a vehicle (for example, a racing cart, a sidecar, or the like) to which a roof or a window is not attached.

Japanese Patent No. 5007132

  By the way, in the vehicle seat, the legs naturally open when seated. For this reason, when the vehicle seat is employed in the driver's seat, for example, it is necessary to consciously point the leg portion to an operation pedal (accelerator pedal, brake pedal, etc.) disposed in front of the vehicle seat. Therefore, it is difficult to improve the operability of the operation pedal.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a vehicle seat in which the occupant's legs are directed inward in the seat width direction and, for example, the operability of the operation pedal can be improved. And

  In order to achieve the above object, the invention described in claim 1 is directed to a seat seat surface (for example, the seat seat surface 6 in the embodiment) that supports the occupant's buttocks and a front end of the seat seat surface. And a leg support (for example, the leg main support 22 in the embodiment) that guides the leg inward in the seat width direction.

  The invention described in claim 2 is characterized in that the leg support is formed with a recess (for example, the recess 24 in the embodiment) that is recessed rearward from the front edge.

  The invention described in claim 3 is characterized in that an inner surface of the inner surface of the recess facing inward in the sheet width direction is inclined inward in the sheet width direction from the upper side to the lower side.

  The invention described in claim 4 is characterized in that the width of the concave portion is increased in the seat width direction toward the front.

  In the invention described in claim 5, side supports (for example, the leg side support 23 in the embodiment) that support the leg from the outside in the seat width direction are disposed at both ends of the leg support in the seat width direction. It is characterized by being.

  According to the first aspect of the present invention, by guiding the occupant's legs toward the inner side in the seat width direction by the leg support, the occupant's legs unconsciously face the inner side in the seat width direction. . Thereby, for example, the operation pedal and the leg can be brought closer in the seat width direction, and the operability of the operation pedal can be improved.

  According to the second aspect of the present invention, the leg portion of the occupant is disposed at a desired position in the recess from above, so that the leg moves so as to fall into the recess. Thereby, a passenger | crew's leg part can be guided toward the inner side of a seat width direction.

  According to the invention described in claim 3, since the inner side surface of the concave portion is inclined toward the inner side in the sheet width direction from the upper side to the lower side, the width in the concave portion is gradually reduced as the width in the sheet width direction is lower. Will do. Therefore, if the leg part falls into the recess, the leg part is easily caught on the inner surface of the recess. Therefore, it can suppress that a leg part passes through a recessed part and is thrown out below rather than the vehicle seat.

  According to the invention described in claim 4, since the width in the seat width direction of the concave portion increases as it goes forward, the amount of lap in the seat width direction between the leg portion and the concave portion increases as it goes forward. become. Thereby, it becomes easy to guide a leg part to the inner side of a sheet | seat width direction as it goes to the front-end | tip of a leg part.

  According to the fifth aspect of the present invention, since the side supports are provided at both ends in the seat width direction of the leg support so as to support the legs from the outside in the seat width direction, the legs are on the outside in the seat width direction. It can suppress moving. Thereby, the opening of a leg part can be suppressed reliably.

It is a perspective view of a vehicular seat concerning this embodiment. It is a front view of the vehicle seat shown in FIG. It is a top view of the vehicle seat shown in FIG. It is sectional drawing which follows the IV-IV line of FIG. It is sectional drawing which follows the VV line of FIG. It is sectional drawing equivalent to FIG. 4 which concerns on the other structure of this embodiment.

  Next, embodiments of the present invention will be described with reference to the drawings.

As shown in FIG. 1, a steering wheel S is disposed in front of the vehicle seat 1. Further, an operation pedal (an accelerator pedal, a brake pedal, etc.) (not shown) is disposed obliquely in front of the vehicle seat 1.

  The vehicle seat 1 is a so-called bucket seat, and holds the occupant D so as to be wrapped from behind and below. The vehicle seat 1 is configured by attaching a pad 3 to a seating surface of a seat frame 2 constituting a skeleton. Specifically, the vehicle seat 1 includes a seat seat surface 6, a seat back 10, a headrest 16, and a leg guide 20.

  In the example of FIG. 1, the above-described seat frame 2 is integrally formed over the entire vehicle seat 1 (the seat seat surface 6, the seat back 10, the headrest 16, and the leg guide 20). The vehicle seat 1 is detachably attached to a stay or the like of a vehicle body (not shown) via a seat frame 2. Further, as shown in FIG. 2, the pad 3 is formed integrally with at least a portion located on the seat seat surface 6 and the leg guide 20. However, the seat frame 2 and the pad 3 may be formed separately in each part of the vehicle seat 1. The seat frame 2 can be formed of, for example, carbon fiber or FRP (fiber reinforced plastic). The skin of the pad 3 is made of a highly waterproof material. An example of the material having a high waterproof property is a PVC (polyvinyl chloride) sheet.

As shown in FIGS. 1 to 3, the seat seat surface 6 mainly supports the buttock of the occupant D. The seat seat surface 6 includes a seat surface main support 7 that supports the occupant D from below, and a seat surface side support 8 that supports the occupant D from both sides in the seat width direction.
The seating surface side support 8 is erected upward from both ends of the seating surface main support 7 in the seat width direction. The inner surface of the seat side support 8 (the surface facing the inner side in the seat width direction) is inclined toward the inner side in the seat width direction as it goes downward.

  The seat back 10 supports the waist and back of the occupant D. The seat back 10 extends upward from the rear end of the seat seat surface 6. The seat back 10 includes a seat back main support 11 that supports the occupant D from the rear, and a seat back side support 12 that supports the occupant D from both sides in the seat width direction. Note that the seat back 10 may be connected to the seat seat surface 6 so as to be tiltable (reclining).

  The seat back side support 12 protrudes forward from both ends of the seat back main support 11 in the seat width direction. As shown in FIG. 1, the seat back side support 12 is formed in a triangular shape in a side view as viewed from the seat width direction. In this case, the amount of forward protrusion of the seat back side support 12 gradually increases as it goes from above to below. Further, as shown in FIG. 3, the inner surface of the seat back side support 12 is inclined inward in the seat width direction toward the rear.

The headrest 16 supports the head and neck of the occupant D. The headrest 16 extends upward from the upper end of the seat back 10. The headrest 16 includes a headrest main support 17 that supports the occupant D from the rear, and a headrest side support 18 that supports the occupant D from the outside in the seat width direction.
The headrest side support 18 protrudes forward from both ends of the headrest main support 17 in the seat width direction. The inner surface of the headrest side support 18 is inclined toward the inner side in the seat width direction toward the rear.

<Leg guide>
As shown in FIGS. 1 to 3, the leg guide 20 supports a portion from the thigh to the knee among the legs of the occupant D. The leg guide 20 extends forward from the front edge of the seat seat surface 6. Specifically, the leg guide 20 includes a leg main support (leg support) 22 that supports the occupant D from below, and a leg side support (side support) 23 that supports the occupant D from the outside in the seat width direction. Have. Note that the design of the range of the leg guide 20 in the front-rear direction can be changed as appropriate. For example, the leg guide 20 may be configured to support only the root portion of the thigh, or may be configured to support the distal end rather than the knee.

4 is a cross-sectional view taken along line IV-IV in FIG. FIG. 5 is a cross-sectional view taken along line VV in FIG.
As shown in FIGS. 2, 4, and 5, the leg main support 22 is inclined downward as the upper surface thereof moves forward. In the example of FIGS. 4 and 5, the upper surface of the leg main support 22 is inclined by decreasing the thickness of the pad 3 toward the front. However, the leg main support 22 may be configured such that the entirety of the seat frame 2 and the pad 3 extends obliquely downward and forward. The inclination angle of the leg main support 22 can be changed as appropriate. In this case, the leg main support 22 may extend horizontally toward the front.
As shown in FIGS. 4 and 5, the upper surface of the leg main support 22 is formed in a straight line along the seat width direction in a cross-sectional view along the seat width direction.

  The leg side support 23 is erected upward from both ends of the leg main support 22 in the seat width direction. The inner surface of the leg side support 23 is inclined toward the inner side in the seat width direction as it goes downward. The width of the leg guide 20 along the seat width direction (the distance between the leg side supports 23) may be uniform over the entire front-rear direction or may be gradually reduced toward the front. Absent.

  As shown in FIG. 1, the upper end edge of the leg side support 23 is positioned above the upper end edge of the seat surface side support 8 described above. In this case, the portion defined by the rear end edge of the leg side support 23, the upper end edge of the seat side support 8, and the lower end edge of the seat back side support 12 constitutes an escape portion 25 opened obliquely upward and forward. ing. The inside of the escape portion 25 is for passing the leg portion of the occupant D in the seat width direction when getting on and off. In the example of FIG. 1, the leg side support 23 gradually decreases in the upward protrusion amount as it goes forward. Further, the front end edge of the leg side support 23 is located in front of the front end edge of the leg main support 22.

  Here, as shown in FIG. 3, a concave portion 24 that is recessed rearward is formed in the center portion in the seat width direction of the leg main support 22 described above. The recess 24 is formed in a V shape in plan view as viewed from above. That is, the concave portion 24 is gradually reduced as the width in the sheet width direction moves from the front to the rear. Therefore, a portion of the leg main support 22 that is located on the outer side in the seat width direction with respect to the concave portion 24 gradually increases as the width in the seat width direction increases from the front toward the rear. The concave portion 24 may be formed at a position offset from the central portion in the sheet width direction.

  As shown in FIGS. 4 and 5, the recess 24 penetrates the leg main support 22 in the vertical direction. Of the inner surface of the recess 24, the inner surface facing the inner side in the sheet width direction is inclined toward the inner side in the sheet width direction as it goes downward. Accordingly, the width of the recess 24 in the sheet width direction is gradually reduced from the upper side to the lower side.

  As shown in FIG. 3, among the inner surfaces of the recess 24, the front end surface facing forward is inclined forward as it goes downward. In this case, the upper rear end edge of the recess 24 reaches the front end edge of the seating surface main support 7. The inclination angle of the inner surface of the recess 24 can be changed as appropriate. Further, the inclination angle of the inner surface of the recess 24 may be varied at various locations in the vertical direction.

  On the other hand, the lower rear edge of the recess 24 terminates in the leg main support 22. However, if the recess 24 is open at least forward, the design range of the formation range in the front-rear direction can be changed as appropriate. For example, the entire vertical direction of the recess 24 may be formed over the entire front-rear direction of the leg main support 22, or may be formed on a part of the leg main support 22 in the front-rear direction. Moreover, the recessed part 24 does not need to penetrate the leg main support 22 at least as long as it is depressed toward the downward direction. 4 and 5, the seat frame 2 and the pad 3 are flush with the inner surface of the recess 24.

<Action>
Next, the effect | action of the vehicle seat 1 mentioned above is demonstrated.
In the seated state on the vehicle seat 1, the occupant D is supported from behind and below by the main supports 7, 11, 17, and 22, and from both sides in the seat width direction by the side supports 8, 12, 18, and 23. Supported. Thereby, the passenger | crew D is wrapped from back, and the position shift to a seat width direction is suppressed.

  In the above-described sitting state, the thigh of the occupant D is guided by the leg guide 20 obliquely downward and forward. Specifically, the thigh is supported from below by the leg main support 22 and supported from the outside in the seat width direction by the leg side support 23.

Here, in this embodiment, it was set as the structure by which the recessed part 24 was formed in the leg part main support 22. FIG.
According to this configuration, as shown in FIGS. 4 and 5, a portion of the thigh located inside the seat width direction (hereinafter, simply referred to as an inner portion of the thigh) is moved upward in the recess 24. Will be placed at the desired position. Therefore, the thigh is guided toward the inner side in the seat width direction by moving so that the inner portion falls into the recess 24. Thereby, since the leg part of passenger | crew D will face the inner side of a seat width direction unconsciously, an operation pedal and a leg part can be made to approach in a seat width direction. Thereby, the operativity of an operation pedal can be improved.

  In addition, in the present embodiment, since the width of the recess 24 in the seat width direction increases toward the front, the amount of wrap in the seat width direction between the inner portion of the thigh and the recess 24 increases toward the front. Will increase. Thereby, it becomes easy to guide the thigh to the inner side in the seat width direction toward the tip of the thigh.

  Furthermore, in this embodiment, since the inner surface of the recess 24 is inclined inward in the sheet width direction as it goes downward from above, the width in the sheet width direction of the recess 24 is gradually reduced as it goes downward. become. Therefore, if the thigh has fallen into the recess 24, the thigh is likely to be caught on the inner surface of the recess 24. Therefore, it is possible to suppress the thigh from passing through the recess 24 and being thrown out below the vehicle seat 1.

  Further, in the present embodiment, since the leg side support 23 that supports the thigh of the occupant D from the outside in the seat width direction is provided, the thigh of the occupant D is prevented from moving outside in the seat width direction. it can. Thereby, the opening of a leg part can be suppressed reliably.

The technical scope of the present invention is not limited to the above-described embodiments, and includes those in which various modifications are made to the above-described embodiments without departing from the spirit of the present invention. In other words, the configuration described in the above-described embodiment is merely an example, and can be changed as appropriate.
For example, in the above-described embodiment, the case where the vehicle seat 1 of the present invention is employed in a racing cart or the like has been described. However, the present invention is not limited to this and can be employed in various vehicles.
In the above-described embodiment, the configuration having the side supports 8, 12, 18, and 23 has been described, but the configuration is not limited thereto. Moreover, you may be the structure which has only one part among each side support 8,12,18,23.

  In the above-described embodiment, the configuration in which the concave portion 24 is formed in the leg main support 22 is described as the configuration for guiding the thigh to the inner side in the seat width direction, but is not limited thereto. For example, like the vehicle seat 1 shown in FIG. 6, the leg main support 122 may be formed in a V shape in a plan view viewed from the front. In this case, the leg main support 122 is inclined downward as it goes inward in the seat width direction. Also by this, the thigh part of the passenger | crew D can be guided toward the inner side of a seat width direction. In the example of FIG. 6, the case in which the entire sheet width direction of the leg main support 122 is formed in a V shape has been described. However, the present invention is not limited thereto, and a part in the sheet width direction is formed in a V shape. It doesn't matter.

  In addition, in the range which does not deviate from the meaning of this invention, it is possible to replace suitably the component in the embodiment mentioned above by the known component, and you may combine each modification mentioned above suitably.
