ADJUSTABLE SEAT MOUNTING MECHANISM

摘要

A seat mounting mechanism (10; 110) for mounting a seat for adjustable fore and aft movement, the mechanism having an elongate fixed rail (12; 112) which is adapted to be secured to a substructure, pan or floor, a movable rail (14; 114) which is engaged with the fixed rail (12; 112) and adapted to be secured to a seat, and at least one locking member (16; 116, 116') mounted on a first one of the fixed rail (12; 112) and the movable rails (14; 114). The locking member (16; 116, 116') is pivotable between and engagement position in which it locks the movable rail (14; 114) relative to the fixed rail (12; 112) and a retracted position in which it frees the movable rail (14; 114) for adjustment along the fixed rail (12; 112). The locking member (16; 116, 116') is mounted on said first rail for pivotable movement, between the engagement and retracted positions, about a pivot axis extending substantially parallel to the rails (12, 14; 112, 114). The locking member (16; 116, 116') has engagement means (62; 162, 162') by which it is selectively engageable with engagement means (29; 129, 129') of, and disposed along, a second one of the rails when the locking member (16; 116, 116') is in its engagement position. The engagement means (62; 162, 162') of the locking member (16; 116, 116') is laterally engageable with the engagement means (29; 129, 129') of the second rail.
