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.
