DESCRIPTION OF THE PREFERRED EMBODIMENTS A seat cushion frame according to the present invention will be described below with reference to a specific example shown in the drawings. FIGS. 1 to 4 show a seat cushion 30 of a rear seat of a passenger car. Embodiment 10 of the seat cushion frame of the present invention which is utilized in the present invention is shown, and the seat cushion frame 10
Is a wire (not shown) having a pair of U-shaped front hooks 33, 33 and one rear hook (not shown).
Is embedded and foamed integrally from resin, and
The seat cushion pad 31 which is to be assembled while being covered with the skin 32 is assembled in advance and the seat
It is used where the cushion 30 is completed.

In the seat cushion frame 10, the pair of pad brackets 16, 16 are connected to the vertical web 1.
8 and a pair of longitudinal flanges 19, 19 formed in a cross-sectional groove so that the pair of U-shaped front hooks 33, 33 of the seat cushion pad 31 can be inserted, and furthermore, the upper end of the longitudinal web 18 Inclined flange 2
1 is extended upward, and the back 2
0, the nut 23 is welded to the bolt holes 22 of the vertical web 18 and the pair of vertical flanges 19, 19 are provided on the frame front 11 at predetermined intervals on the left and right.
At the rear of the frame front 11. More specifically, the pair of pad brackets 16,
16 folds a joining lip 24 outwardly on the upper portion of each of the pair of longitudinal flanges 19, 19, and the joining lips 24, 24 allow the frame front 11 to be bent.
To be welded. In particular, the joining lips 24, 24 are bent lips to fit the pipe cross section of the frame front 11.

[0007] The pad brackets 16 and 16 are formed by blanking a blank from a steel plate to a predetermined shape and size, and punching and bending the blank.
Is completed where the vertical web 18 is welded to the back surface 20 of the vertical web 18 in a state where the holes are aligned.

In the seat cushion frame 10, reference numeral 12 denotes a frame rear, reference numerals 13 and 14 denote frame sides, reference numerals 15 and 15 denote vertical frame members, and reference numeral 17 denotes a hook.

Next, an operation of assembling the seat cushion pad 31 to the seat cushion frame 10 will be described. First, the seat cushion pad 31 is fitted to the pad brackets 16, 16 with the front hooks 33, 33, and the seat cushion pad 31,
It is placed on the cushion frame 10. At this time, the front hooks 33, 33 are guided in the front-rear direction by the frame front 11 and the inclined flange 21, and are guided in the left-right direction by the pair of vertical flanges 19, 19 to prevent the pad from slipping.・ Bracket 16,
16 is easily and quickly inserted into the bolt holes 22 and 22 so that the rear hooks are also hooked on the hook hooks 17. Next, the bolts 25, 25 are inserted into the bolt holes 22, 22.
Through the nuts 23, 23. In this way, the front hooks 33, 33 are fixed to the pad bracket 16 in the front-rear and left-right directions so that they can be positioned, and the seat cushion frame 10 can simplify the seat cushion pad 31. To be able to be assembled.

As will be apparent from the specific embodiments of the present invention described above with reference to the drawings, one of ordinary skill in the art to which the present invention pertains will appreciate the subject matter of the present invention. Is the nature of the invention (na
