Adjusting device for a seat

摘要

In an adjusting device for a seat in a motor vehicle, a sliding seat guiding mechanism moves the seat in a generally horizontal direction. The guide mechanism includes an upper part secured to the seat and a support member secured to the floor of the vehicle. A rack is attached to the upper part and is driven by a pinion mounted on the support member for moving the seat in the generally horizontal direction. The rack is adjustably mounted on the upper part to permit limited movement of the rack in the generally vertical direction disposed transversely of the generally horizontal direction of movement of the seat so that proper engagement of the rack and the pinion is assured.
