Automobile seat and stand-alone seat cushion extension device

Abstract

The invention discloses an automobile seat and a stand-alone seat cushion extension device. Three locking pins on an unlocking handle (3) are matched with clamping grooves; a first locking pin (33) isinserted into a first clamping groove (27), and a third locking pin (35) is inserted into a third clamping groove (29) to limit the sliding direction of an extending plate (1) and a fixing plate (2).A second locking pin (34) is inserted into a second clamping groove (28) to limit the vertical direction of the sliding direction of the extension plate (1) and the fixing plate (2), and the fixationof the whole extension plate (1) in the front-back and left-right directions is controlled. During unlocking operation, the unlocking handle (3) is pressed downwards, the locking pins are separated from the clamping grooves, the extension plate (1) and the unlocking handle (3) move forwards and backwards together, and the three locking pins are inserted into the clamping grooves in the current position to complete locking. And the sliding shaft and the sliding limiting groove are formed between the two relatively sliding structures, so that the overall structure is simple, the cost is reduced, and the stability and reliability of sliding motion are improved.
