Description

  The present invention relates to a structure for mounting a flip-up type vehicle seat, and more particularly, to a structure for mounting a vehicle seat having a structure in which a seat body is stored by being raised toward a vehicle compartment wall.

In this type of vehicle seat, the side surface of the seat cushion is rotatably coupled to a shaft body installed between a pair of brackets provided on the vehicle body, and the seat body is flipped up and stored toward the compartment wall of the passenger compartment. It is possible. In this case, there is one in which a spring member is provided around the shaft body to apply a supporting force when the sheet is flipped up. Patent Document 1 discloses a flip-up type vehicle seat provided with a spring member that applies a support force when the seat is flipped up.
JP 2005-96633 A

  However, the conventional flip-up type vehicle seat has a problem that the bracket receiving the reaction force of the spring member is easily deformed and a sufficient seat-up assisting force cannot be obtained.

  Therefore, the present invention solves such a problem, and an object of the present invention is to provide a structure for mounting a flip-up vehicle seat that can obtain a sufficient seat-lifting assisting force.

  In order to achieve the above object, in the first invention, the side surface of the seat cushion (S1) can be rotated on the shaft body (1) installed between the pair of brackets (3A, 3B) provided on the vehicle body (41). In combination, the seat body (S) can be flipped up and stored toward the compartment wall of the passenger compartment, and the spring member (7A, 7B) is disposed around the shaft body (1) to raise the seat. In the structure for mounting a flip-up type vehicle seat so as to give an assisting force, a connecting member (6) for connecting the brackets (3A, 3B) is provided, and the intermediate position of the connecting member (6) is set at the vehicle. Secure to the body (41).

  In the first invention, since the intermediate position of the connecting member is fixed to the vehicle body, even if the reaction force of the spring member is input, this is quickly received by the vehicle body via the intermediate position. Therefore, the bracket is not deformed, and a sufficient raising assist force can be obtained.

  In this 2nd invention, a mounting bracket (8) is provided in the upper edge part of the wheel house inner panel (41) which comprises the said vehicle body, The intermediate position of the said connection member (6) is set to the said mounting bracket (8). Fix it. In the second invention, the upper edge portion of the wheel house inner panel is close to the abutting portion with the wheel house outer panel and has high rigidity, so that the deformation of the bracket is further effectively prevented and a sufficient raising force is obtained. be able to.

  In the third invention, a positioning pin (62) is provided on the lower surface of the intermediate position of the connecting member (6), and a guide hole (851) through which the positioning pin (62) enters the mounting bracket (8). In the third aspect of the invention, relative positioning of the shaft body with respect to the chamber wall can be performed easily and reliably.

  In addition, the code | symbol in the said parenthesis shows the correspondence with the specific means as described in embodiment mentioned later.

  As described above, according to the flip-up vehicle seat mounting structure of the present invention, it is possible to obtain a sufficient seat flip-up assisting force, and the seat body can be easily flipped up and stored.

  FIG. 1 shows the appearance of a flip-up vehicle seat. In FIG. 1, the seat body S is supported by a folding support leg L provided on the lower surface of the seat cushion S <b> 1 at the vehicle inner side edge, and supported by the hinge device H at the vehicle outer side edge. The hinge device H includes a horizontal shaft body 1, and the seat body S is rotatably coupled to the shaft body 1 by stays 21 and 22 at the front and rear positions thereof.

  The front and rear end portions of the shaft body 1 are installed on the support brackets 3A and 3B, respectively, and the lower end of the front and rear support brackets 3A and 3B is a wheel house inner panel 41 constituting a vehicle body as shown in FIGS. Are fixed to mounting brackets 51 and 52 provided on the surface. Further, the front and rear support brackets 3A and 3B are connected to each other by fixing both ends of a connecting member 6 that is formed in a substantially U-shaped cross section (see FIG. 5) that opens in the vehicle interior direction and extends horizontally in the vehicle front-rear direction. Yes. A pair of coil springs 7A and 7B are disposed around the shaft body 1 at the front and rear positions. Each end 71 of the coil springs 7A and 7B is fixed to the plate surface of the connecting member 6, and the other end 72 is fixed to the stays 21 and 22. Thus, the assisting force when the sheet is flipped up is applied to each of the stays 21 and 22.

  A mounting hole 61 (FIG. 5) is provided on the side surface of the connecting member 6 at an intermediate position near the rear of the vehicle, and a positioning pin 62 is provided downward on the lower surface of the connecting member 6 corresponding to the mounting hole 61. Projected. On the other hand, the wheel house inner panel 41 is further provided with a mounting bracket 8 between the front and rear mounting brackets 51 and 52 (FIG. 4), which is formed in a hat cross section having flange portions 81 on both sides. The flange portion 81 is joined and fixed to the upper edge portion of the wheel house inner panel 41 having high rigidity close to the abutting portion with the wheel house outer panel 42 (FIG. 5).

  As shown in FIG. 5, the mounting bracket 8 has a substantially L-shaped cross section having a vertical wall 82 and a horizontal wall 83 as shown in FIG. 5. A mounting hole 821 having 84 is formed. Further, a square opening 831 is formed in the horizontal wall 83, and a guide member 85 is fitted therein. A guide hole 851 is formed at the center of the guide member 85, and an upper surface thereof is a guide surface 852 that is inclined toward the guide hole 851.

  In such an attachment structure, when the seat body S is attached, the hinge device H is lifted by the installation robot together with the seat body S integrally joined thereto (the seat body is omitted in FIG. 4), and the positioning pin 62 is guided. The member 85 (FIG. 5) is lowered to enter the guide hole 851. The positioning pin 62 enters the guide hole 851 smoothly by guiding the tip of the pin along the inclination of the guide surface 852. Accordingly, the hinge device H (and the seat body S) is positioned in the vehicle width direction.

  In this state, the attachment hole at the lower end of the front support bracket 3A is made to coincide with the attachment hole on the upper surface of the front attachment bracket 51 (FIG. 4), and bolts 91 (FIG. 3) are inserted into these to fix them together. Thus, after positioning the hinge device H at two points by the front support bracket 3A and the positioning pin 62, the remaining rear support bracket 3B is coupled to the rear mounting bracket 52 (FIG. 4) with the bolt 91 (FIG. 3). Fix it. Thereby, the inclination in the planar view of the hinge apparatus H can be suppressed to the minimum.

  When the front and rear support brackets 3A and 3B are fixed, the mounting hole 61 of the connecting member 6 coincides with the mounting hole 821 of the mounting bracket 8, so that bolts 92 (FIG. 5) are inserted into these and coupled to the weld nut 84. Thus, the intermediate position of the connecting member 6 is fixed to the wheel house inner panel 41 via the mounting bracket 8.

  By fixing the intermediate position of the connecting member 6 to the upper edge of the highly rigid wheel house inner panel 41 as described above, even if the reaction force of the coil springs 7A and 7B is input, this can be promptly performed via the mounting bracket 8. The wheel house inner panel 41 is received at the upper edge. Therefore, the front and rear support brackets 3A and 3B are not deformed, and a sufficient raising assist force can be obtained.
