る。2. Description of the Related Art Rotating a passenger seat 180 degrees from the front to the rear is widely used with the spread of one-box cars. A seat rotation device for this purpose has an upper rail having a circular sliding portion that is in a fixed relationship with the seat cushion frame, and a circular sliding portion that is fixed to a floor member of the vehicle and is slidable with the sliding portion of the upper rail. The lower rails and the lock between both rails and the mechanism for releasing them are the basic constituent features. The basic constitutional requirements of such a rotating seat device are, for example, Japanese Utility Model Publication No. 63-130.
No. 65 and Japanese Utility Model Publication No. 1-40773.

In the above-mentioned Japanese Utility Model Publication No. 63-13065, a substantially triangular reinforcing portion that extends laterally outward is formed on both left and right sides of a turn bracket corresponding to an upper rail fixed to a seat cushion frame.
A seat belt anchor is bolted to this reinforcing portion.
In another example, Japanese Utility Model Publication No. 1-40773, a seat belt anchor is bolted to a pipe extending to the left and right of a rear portion of a seat cushion frame via a bracket.

In the latter publication, the reinforcing member is attached to the pipe. It is necessary to weld and prevent upward deformation of the central part of the pipe when a large load is applied to the seat belt, and this reinforcing member impairs the comfort of the seat cushion. Therefore, it is an object of the present invention to solve the above-mentioned problems of the conventional technology.

It has a central connecting member 5 and reinforcing members 6, 6 for connecting the front frame 2 and the side frames 3, 3. Seat cushion frame 1
Is made of steel mold material, pipe, or aluminum alloy extruded mold material. The side frames 3 and 3 have a substantially U-shaped cross section having inwardly facing flanges 7 and 7, and the end faces of the pipe-shaped rear frame 4 are brought into contact with the rear parts to weld them together.
The front portions of the side frames 3 and 3 are bent inward by approximately 90 degrees, and the end faces of the front frame 2 having a substantially U-shaped cross section are welded to the end faces. Both ends of the rear frame 4 are seat belt anchor attachment portions 8. 9 is a seat cushion attachment portion (not shown).

せると、側枠3、3との間に三角形部Bを作る。The seat rotating device further includes a rail assembly 10. The rail assembly 10 has a sliding portion 11 at the edge of the hole in the center thereof. The annular sliding portion 11 serves as an annular sliding portion between the upper rail and the lower rail. The front corner of the rail assembly 10 is bolted to the reinforcing members 6, 6 and the front frame 2 at or near the fixing point. The rear corner portion of the rail assembly 10 is bolted to the bracket 12 of the rear frame 4 at a position behind the fixing point. As a result, when the rail assembly 10 is bolted to the seat cushion frame 1, a triangular portion B is formed between the side cushions 3 and 3.

させ得る。At the time of a vehicle collision, an external force acts diagonally upward on the rear frame 4 via the seatbelt anchor mounting portion 8. The forward and diagonal upward component forces of this external force are triangular portions A,
It is dispersed by the members constituting B, and in particular, the reinforcing members 6, 6
Absorbs this external force. Therefore, the force for separating the upper rail of the rail assembly from the lower rail can be minimized.
