When the lock assembly 7 is installed on the seat cushion 3 side by the vehicle seat according to the embodiment of the present invention and pulls the band 37 connected to the latch 10, the lock assembly 7 strikes the striker 5. ), The seat cushion (3) stands up, and the striker (5) is a round bar, and the indentation (9) is tapered to the end, so that the seat cushion (3) stands up. There is an advantage that the insertion with the fitting portion 9 is performed smoothly.

In addition, this invention is not limited by the said Example, A various deformation | transformation is possible in the range which does not deviate from the summary. For example, the round bar of the striker may be replaced with a bar having a large cross section, or a rib having a tapered surface with a thin tapered surface may be provided on the rear surface of the indent.

According to the present invention of claim 1, the lock assembly is provided with a retaining member fixed to a cushion panel which rotates integrally with a seat cushion, and a latch which is urged in a direction protruding and guided freely to the retaining member, The retaining member is provided with a tapered tapered portion, and the striker has a tapered tapered portion by installing a fitting lug portion that latches the protruding state while the seat cushion fits. The lock assembly can be smoothly fastened to the striker, and the seat cushion is knocked down by providing a motion control structure for positioning the lock assembly in the transverse direction and regulating the motion with the fitting portion inserted into the fitting stop. In this state, it is possible to reliably eliminate lateral shaking, and the end of the seat cushion When connecting the protruding tension member and pulling the tension member against the bias in the protruding direction of the latch when the seat cushion falls, the seat cushion stands up by simply pulling the tension member by standing up. Since it can stand, the effect which is very convenient can be achieved. In the present invention described in claim 2, a metal material is used for the striker, and a resin material is used for the tapered indentation so that no abnormal noise is produced. The present invention described in claim 4 is a latch. The seat cushion is secured by allowing the lock assembly to be fastened to the striker only with the weight of the seat cushion having a slanted inclined end that receives a pressing force that touches the striker and moves the latch in the direction of entry when the seat cushion is knocked over. Even when knocked over, the effect is very convenient.
