Description

[Detailed Description of the Invention] The present invention relates to a seat belt retractor mounting structure for an automobile.

In recent years, many retractable seatbelts have been adopted for automobiles, the length of which can be adjusted according to the physique of the occupant.
When a seat belt retractor is fixed to a floor panel under the rear seat, a wall inside the vehicle, etc., the retractor protrudes into the vehicle interior, resulting in problems such as spoiling the exterior appearance. Furthermore, a large tensile load is applied to the retractor mounting portion when a car crashes, but simply mounting the retractor on a floor panel may not be able to withstand the load. There is a problem. In contrast, as disclosed in Japanese Utility Model Application Publication No. 53-60220, a part of the plate for attaching the seat belt fixed to the floor panel is extended and joined to the side frame, and the load is transferred to the side frame. Although there are attempts to share the burden, it cannot be said that the load is distributed sufficiently.

In view of this, the present invention forms a recess in the rear wheel house, installs a retractor in the recess, and covers the outside with trim, thereby eliminating the protrusion of the retractor into the passenger compartment and attaching the retractor. An object of the present invention is to provide a seat belt retractor mounting structure for an automobile in which the load-bearing strength of a retractor mounting portion is improved by mounting a nut plate as a bridge between a rear wheel house and a rear side frame.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described below with reference to the drawings.

In the structure of the rear interior of an automobile shown in Fig. 1, 1 is a rear seat, 2 is a seat belt, 3 is a rear wheel house, 4 is a floor panel, and 5 is a rear side frame. In this figure, the right side portion 2b is attached to the floor panel 4 below the center of the rear seat 1. The right side portion 2b is attached to the floor panel 4 below the center of the rear seat 1.

The retractor mounting structure on the rear wheel house side is shown in FIGS. 2 and 3.
That is, the rear wheel house 6 has a recess 8 recessed toward the outside of the vehicle at a position that does not interfere with the suspension tower 7 at the front thereof, and a retractor 9
is provided in the recess 8 and covered with a trim 10 from the passenger compartment side. A bracket 11 protrudes downward from the bottom of the retractor 9, and the bracket 11 is connected to a nut plate 12 provided on the bottom side of the floor panel.
It is fixed with bolts 13 passing through the floor panel 4.

The nut plate 12 is shown in FIG. 4, and includes a top wall portion 15 with a nut 14 fixed to its lower surface, a U-shaped side wall portion 16 connected to the top wall portion 15, and a U-shaped side wall portion 16 connected to both ends of the side wall portion 16. installed side flange 17,1
7, and a central flange 18 extending downward from the edge of the top wall 15 between the flanges 17, 17 on both sides. Then, nut plate 12
With the top wall 15 in contact with the lower surface of the floor panel 4, the side wall 16 is connected to the rear wheel house 6 in the recess 8, and the side flanges 17, 17 and the center flange 18 are connected to the rear side frame 5. has been done. That is, the nut plate 12 is attached so as to bridge between the rear wheel house 6 and the rear side frame 5.

In the above structure, since the retractor 9 is housed in the recess 8 of the rear wheel house 6, it does not protrude into the vehicle interior. In addition, since the nut plate 12 to which the retractor 9 is attached is bridged and fixed between the rear wheel house 6 and the rear side frame 5, even if a large tensile load is applied to the retractor attachment part of the seat belt 2 due to an automobile collision, the load will be suppressed. The nut plate 12 is distributed to the rear wheel house 6 and the rear side frame 5 through the nut plate 12 to prevent deformation of the floor panel 4 and the nut plate 12.
Peeling is prevented. Also, nut plate 12
Since the side wall portion 16 and the rear side frame 5 form a so-called box with a closed cross-section structure, the load-bearing strength of the retractor mounting portion is high.

As described above, according to the present invention, since the retractor is housed in the recess in the rear wheel house and covered with the trim, the retractor does not protrude into the vehicle interior, improving the appearance of the vehicle interior, and improving the appearance of the vehicle interior. The nut plate to which the retractor is attached is fixed across the rear wheel house and rear side frame, which has the excellent effect of increasing the load-bearing strength of the retractor mounting area.
