detailed description

Below in conjunction with the embodiment shown in the accompanying drawings the utility model is further described.

A seat retractable mechanism includes a front mounting foot 1 and a floor lock 2 , a cushion frame 3 , a floor lock 4 , a front link 5 and a rear link 6 installed on a vehicle body. The floor latch 2 is fixed on the vehicle body by welding. The cushion frame 3 is connected with the front mounting leg 1 by the front connecting bolt 7 . The connection mode between the floor lock 4 and the cushion frame 3 allows the floor lock 4 to be rotated and received in the cushion frame 3 . Fig. 3 is a schematic structural view of the seat retractable mechanism, Fig. 4 is a side view thereof, Fig. 5 is a side view during and after stowage, and Fig. 6 is a top view thereof.

The floor lock 4 is paired with the floor lock 2 to allow the floor lock 4 to be locked by the floor lock 2 .

Cushion skeleton 3 is connected with front mounting foot 1 at the front end, and is connected with floor lock 4 at rear end. The front end of the front connecting rod 5 is fixedly connected with the front mounting foot 1, the rear end is connected with the front end of the rear connecting rod 6, and the rear end of the rear connecting rod 6 is fixedly connected with the floor lock 4. The front end of the front connecting rod 5 is riveted with the front mounting foot 1 by a step rivet, and the rear end of the rear connecting rod 6 is riveted with the floor lock 4 by a step rivet. The cushion frame 3 comprises guide grooves on the side, and the direction of the guide grooves is the front and back direction of the seat, that is, the longitudinal direction of the seat. The junction of the rear end of the front connecting rod 5 and the front end of the rear connecting rod 6 is flexibly connected in the guide groove, so that the junction can move along the guide groove. In this embodiment, the rear end of the front connecting rod 5 and the front end of the rear connecting rod 6 are riveted through a step rivet 12, and the step rivet 12 is movably installed in the guide groove of the cushion frame 3, so the step rivet 12 can be moved along the The channel is active.
