First Claim
1. A lifter device and vehicle seat combination, designed to lift and lower a seat cushion with respect to a floor member provided on a floor of a vehicle body, comprising:
- a pair of front and rear links each coupling a side frame of the seat cushion and the floor member;
a front bracket and a rear bracket each of which is fixed to the floor member and to which respective lower ends of the front link and the rear link are swingably coupled;
a front hitting segment formed in a front portion of the side frame and located in spaced-apart relation to a front catch segment formed in the front bracket, the front hitting segment having a shape conforming with that of the front catch segment; and
a rear hitting segment formed in a rear portion of the side frame and located in spaced-apart relation to a rear catch segment formed in the rear bracket, the rear hitting segment having a shape conforming with that of the rear catch segment,wherein;
when the side frame is displaced in the frontward direction along with a deformation of the front and rear links due to an impact force during a frontal collision, the front hitting segment of the side frame is caught and stopped by the front catch segment of the front bracket; and
when the side frame is displaced in the rearward direction along with a deformation of the front and rear links due to an impact force during a rear collision, the rear hitting segment of the side frame is caught and stopped by the rear catch segment of the rear bracket.

Abstract
A vehicle seat lifter includes front and rear links with upper ends pivoted to a side frame of the seat and lower ends pivoted to front and rear floor brackets. A front hitting segment is in a front portion of the side frame spaced from a front catch in the front bracket, and a rear hitting segment is in a rear portion of the side frame spaced from a rear catch in the rear bracket. The front hitting segment is stopped by the front catch when the side frame is displaced frontward along with a deformation of the front and rear links due to forces during a frontal collision. The rear hitting segment is stopped by the rear catch when the side frame is displaced rearward along with a deformation of the front and rear links due to forces during a rear collision.
