Double-fold unlocking device of vehicle rear seat

Abstract

The present invention relates to a double-fold unlocking device of a rear seat of a vehicle, comprising: a seat cushion hinge bracket mounted at the rear part of a seat cushion frame to rotate integrally with the seat cushion frame; a lever bracket rotatably assembled to the seat cushion hinge bracket about a first rotation axis; a link bracket, the lower part of which is rotatably assembled to the upper arm of the lever bracket, and the upper part of which is linked with the rotation of a backrest hinge bracket mounted at the lower part of a seat cushion frame; and a lock release cable assembly whose rear end is assembled to a forearm of the lever bracket to release locking of the seat cushion frame with respect to a vehicle body floor when the lever bracket rotates. According to the double-fold unlocking device of the vehicle rear seat of the present invention, when a rear seat back is rotated in an opposite direction when the rear seat back is folded or unfolded, extrusion and deformation caused by engagement between bracket members can be prevented.

Description

technical field [0001] The present invention relates to a double-folding unlocking device for a rear seat of a vehicle, in particular, to a double-folding unlocking device for a rear seat, which prevents the Crushing and deformation due to snapping between bracket components. Background technique [0002] Generally, a seat of a vehicle is composed of a seat cushion installed on a vehicle body floor and a seat back rotatably installed on the seat cushion. [0003] The seat back is rotatably installed on the rear end of the seat cushion through a recliner, and the angle can be adjusted through the recliner. [0004] The recliner connects the lower part of the seat back and the rear of the seat cushion, and the rotation of the seat back can be unlocked when the recliner is operated, so that the seat back can be folded toward the seat cushion side or backward. [0005] On the other hand, in the case of the double-folding rear seat, when the recliner is operated, the seat cushi...
