Description

  The present invention relates to an armrest for a vehicle seat and a mounting structure thereof.

  Some vehicle seats are provided with armrests. Various types of armrests are known, such as those that can be adjusted in angle and those that are accompanied by an accessory case (see, for example, Patent Document 1 below).

JP 2003-182429 A

  Since the conventional armrest does not support the entire arm of the occupant, there is a problem that the burden on the occupant is large. In addition, a situation in which the occupant's arm slips off the support surface of the armrest is likely to occur.

  The problem to be solved by the present invention is to provide an armrest for a vehicle seat and its mounting structure that can reduce the burden on the passenger.

  In order to solve the above problems, an armrest for a vehicle seat according to the present invention has an arm rest portion formed of a deformable material, with one end on the seat back and the other end on the seat back. It is connected to a member located further forward.

  It has a support part formed of a material that is lower in elasticity than the arm rest part, supporting the arm rest part, and one end part of the support part is on the seat back, and the other end part of the support part Is preferably connected to a member positioned in front of the seat back.

  In order to solve the above problems, the mounting structure of the armrest of the vehicle seat according to the present invention includes a position where one end of the armrest of the vehicle seat is connected to the seat back, and an end of the other side. Position adjustment means capable of changing at least one of positions connected to members positioned in front of the seat back is provided.

  According to the armrest of the vehicle seat according to the present invention, the arm rest portion formed of a deformable material is attached so as to bridge the seat back and a member provided in front of the seat back. Therefore, the area to support the arm is larger than that of the conventional armrest (for example, the part from the elbow to the shoulder is also supported), and the part formed of the deformable material of the arm rest fits the arm This reduces the burden on the passenger.

  If the armrest is attached by a support portion made of a material having lower elasticity than the arm rest portion, the stability of the armrest is increased. Also, when the vehicle is collided from behind, when the occupant is pressed backward, the seat back and the member located in front of it are connected via the support part, so the seat back falls back. Can be suppressed. That is, by providing the support part, not only the function as an armrest can be improved, but also the safety of the vehicle can be improved.

  According to the armrest mounting structure according to the present invention, the position of the position where one end of the armrest is connected to the seat back, and the position of the position where the other end is connected to the member positioned forward of the seatback, Since it is possible to change at least one of these, it is possible to finely adjust the position according to the physique.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Unless otherwise specified, the front-rear direction in the following description refers to the forward / backward direction of the vehicle on which the vehicle seat armrest 1 is mounted, and the vertical direction refers to the vertical direction of the vehicle. The width direction means the width direction of the vehicle and the direction perpendicular to the front-rear direction and the up-down direction.

  The vehicle seat armrest 1 according to the present embodiment whose appearance is shown in FIG. 1 (hereinafter also simply referred to as the armrest 1) includes an arm rest portion 11 and a support portion 12. As will be described later, the arm rest portion 11 is a portion that supports an occupant's arm, and at least a portion thereof is formed of a deformable material. It is preferable that the material constituting the arm rest portion 11 is a stretchable cloth material as a whole. The arm rest portion 11 in the present embodiment is entirely formed of a net-like (mesh) material.

  The support part 12 is a member for supporting the arm rest part 11. Although the material which comprises the support part 12 is deformable, what is necessary is just a material with lower elasticity than the arm rest part 11. The support portion 12 in the present embodiment is a wire that satisfies the condition. The arm rest portion 11 is formed of a net-like cloth material in a bag shape, and a wire serving as a support portion 12 is passed through the inside thereof. The support portion 12 is passed through so as to be located on the outer side in the width direction of the “bag”.

  As shown in FIG. 2, the armrest 1 according to the present embodiment is directly or indirectly attached to a member whose one end of the support portion 12 is positioned on the seat back 70 and whose other end is positioned forward of the seat back 70. Is attached by being connected to. An example of the mounting structure (the mounting structure of the armrest 1 according to one embodiment of the present invention) is as follows.

  A hooking member 30 (hereinafter referred to as a first hooking member 30 to distinguish it from a second hooking member described later) is attached to the upper side of the side surface of the seat back 70. The first hook member 30 is a member in which an annular groove 31 into which the support portion 12 that is a wire can enter is formed around the first hook member 30. The first hook member 30 can change the position in the longitudinal direction of the seat back 70 (position in the vertical direction) (position adjustment means on the seat back 70 side is provided). Any mechanism for changing the mounting position of the first hooking member 30 may be used.

  An example will be described with reference to FIGS. A plurality of engaged portions 731 (screw holes) arranged in the longitudinal direction are provided on the side surface of the seat back 70 (see FIGS. 2 to 4 and the like). The first hook member 30 is formed with an engaging portion 32 (male screw portion) that can be engaged with the engaged portion 731 (see FIGS. 4 and 5A). The bracket 73 is fixed to the frame 72 that supports the pad 71 that is a cushion material, the engaging portion 32 is formed on the bracket 73, and then the engaging portion 32 is exposed from the skin 74 that covers the pad 71. The pad 71 is formed with an opening 711 that exposes the surface of the bracket 73 on which the engaging portion 32 is formed (see FIG. 5 and the like).

  With such a configuration, the mounting position of the first hooking member 30 can be changed by changing the position of the engaged portion 731 with which the engaging portion 32 engages (stepwise adjustment is possible). Is).

  Although not shown, the first hooking member 30 is slidably connected in the longitudinal direction of the seat back 70, and the occupant can fix the first hooking member 30 at an arbitrary position (stepless adjustment is possible. You may do it.

  Various “members positioned in front of the seat back 70” to which the other side end portion of the armrest 1 (support portion 12) is directly or indirectly connected are conceivable. For example, an instrument panel (hereinafter referred to as instrument panel 90) (first example) or a seat cushion 80 (sitting portion) (second example) can be considered.

  A first example will be described. Any connection structure to the instrument panel 90 at the other end of the armrest 1 (supporting portion 12) may be used. For example, as shown in FIGS. 1, 6, etc., a hook member 13 is provided at the other end of the support portion 12, and a hole or member (hooked portion 91) in which the hook member 13 is hooked is provided in the instrument panel 90. Structure. That is, the other side end portion of the support portion 12 is hooked on the instrument panel 90 (the hooked portion 91) via the hook member 13. In this case, in order to be able to adjust the position in the up-down direction of the other side end portion of the armrest 1, the instrument panel 90 may be provided with a plurality of hooked portions 91.

  Although not shown, the hook member 13 as described above may not be provided, and the support portion 12 that is a wire may be directly hooked at the other end portion of the armrest 1. In that case, a hooking member (to be distinguished from the first hooking member 30, hereinafter referred to as the second hooking member) to which the support portion 12 on the other end side of the armrest 1 is hooked is attached to the instrument panel 90. It is good also as a structure. In this case, it is preferable that the mounting position of the second hooking member with respect to the instrument panel 90 can be changed. Any mechanism for changing the mounting position of the second hooking member may be used. A structure similar to that of the first hooking member 30 described above can be applied.

  As described above, the armrest 1 according to this example has one end portion connected directly or indirectly to the seat back 70 and the other end portion connected directly or indirectly to the instrument panel 90. In this example, the position where one end of the armrest 1 (supporting portion 12) is connected to the seatback 70 can be adjusted (position adjusting means on the seatback 70 side is provided), and the armrest The position at which the other end of 1 (support 12) is connected to the instrument panel 90 can also be adjusted (position adjustment means on the instrument panel 90 side is provided). That is, it is possible to adjust the positions of both one end (seat back 70 side) and the other end (instrument panel 90 side) of the armrest 1 (support portion 12).

  The effect | action by setting it as such a structure is as follows. In this example, the arm rest portion 11 formed of at least a part of a deformable material is attached so as to bridge the seat back 70 and a member provided in front of the seat back 70. Compared to the conventional armrest 1, the area for supporting the arm becomes larger (for example, the part from the elbow to the shoulder is also supported), and the part formed of the deformable material of the arm rest part 11 fits the arm. This reduces the burden on the passenger.

  Moreover, since the support part 12 of the armrest 1 is formed of a material having lower elasticity than the arm rest part 11, the stability of the armrest 1 is increased. Further, when the vehicle is collided from behind, when the occupant is pressed backward, the seat back 70 is connected to the instrument panel 90 located in front of the seat back 70 via the support portion 12. Can be prevented from falling behind. That is, by providing the support portion 12, not only the function as the armrest 1 can be improved, but also the safety of the vehicle can be improved.

  Moreover, since the position adjustment means for adjusting the position of the end of the armrest 1 is provided on both the seat back 70 side and the instrument panel 90 side, fine position adjustment according to the physique can be performed.

  The second example will be described focusing on differences from the first example. As shown in FIG. 7, a relay member 81 extending upward is connected to the seat cushion 80. The relay member 81 is rotatably connected to the side surface of the seat cushion 80. The other end portion of the armrest 1 (support portion 12) is connected to the upper side (the upper end in this example) of the relay member 81. In the present embodiment, a structure in which the angle of the relay member 81 (relative position of the relay member 81 with respect to the seat cushion 80) can be adjusted step by step using a so-called ratchet mechanism is constructed. As long as the relay member 81 can be fixed so as not to be easily displaced at a predetermined angle, any connection structure may be used for the relay member 81 and the armrest 1.

  If the relay member 81 is rotated forward, the location where the relay member 81 and the armrest 1 are connected is displaced forward. If the relay member 81 is rotated backward, the location where the relay member 81 and the armrest 1 are connected is displaced backward. That is, the position of the other end portion of the armrest 1 (supporting portion 12) can be changed by the rotation of the relay member 81 (including a position adjusting means on the seat cushion 80 side).

  By adopting such a configuration, the same operation as the first example is achieved. In addition, as shown in FIG. 7B, the relay member 81 that is pivotally connected to the seat cushion 80 is pivoted rearward (as viewed from the width direction, the entire relay member 81 is seated). The relay member 81 is rotated to a position overlapping the cushion 80), so that one end of the armrest 1 is connected to the seat back 70 and the other end is connected to the relay member 81 (seat cushion 80). The armrest 1 that is not to be accommodated can be accommodated (a state that does not interfere with the occupant).

  As mentioned above, although embodiment of this invention was described in detail, this invention is not limited to the said embodiment at all, A various change is possible in the range which does not deviate from the summary of this invention.

  The armrest 1 according to the embodiment described above has one end connected to the seat back 70 and the other end connected to a member located in front of the seat back 70, and the connection position can be adjusted. However, like the armrest 1a shown in FIG. 8, you may provide the length adjustment means 14 which can adjust the length of armrest 1 itself. As the length adjusting means 14, the arm rest portion 11 and the support portion 12 are partially overlapped, and the length of the overlapping portion is changed to adjust the length of the entire armrest 1a. Can be illustrated.

  In this case, the length adjusting means 14 cannot be provided if the wire that is the support portion 12 cannot be bent and deformed freely. In that case, armrest 1a shall consist of the part comprised from the arm rest part 11 and the support part 12, and the other part (part comprised from the cloth material which can be bent and deformed), the said other than that It is only necessary that the length of the armrest 1a can be adjusted by adjusting the length of the portion.

  Although the armrest 1 according to the above embodiment has been described as having the arm rest portion 11 and the support portion 12 (wire) that supports the arm rest portion 11, the armrest 1 may be configured not to include a portion corresponding to the support portion 12. . For example, like the armrest 1b shown in FIG. 9, the seat back 70 and the seat back 70 are disposed at the front ends of the belt-like cloth material 15 (for example, a cloth material made of polyester fiber) that has low elasticity but easily deforms. It is good also as a structure provided with the structures 16 and 17 for connecting to the member located. That is, the cloth material 15 itself may be configured as the arm rest portion 11 and the support portion 12 in the above embodiment. Length adjusting means 14 for adjusting the entire length of the cloth material 15 can also be provided. However, like the armrest 1 according to the above-described embodiment, the arm rest portion 11 having a relatively high elasticity and the support portion 12 having a relatively low elasticity can be fitted to the occupant's arms. It will be a thing. In other words, in the above-described embodiment, the arm rest 1 is made of a highly stretchable material, so that the armrest 1 is greatly bent downward by the weight of the arm while increasing the degree of adhesion of the armrest 1 to the occupant's arm. Is suppressed by the support portion 12.
