Passenger vehicle seat on crossbar uses crossbar undercut for conformably shaped projection on seat to engage undercut when inserted and be held there by holding element for stability.

摘要

On its first side (4) facing the seat (1) the crossbar (2) has an opening (3) which extends from side (4) to crossbar and is undercut such that the wall of the undercut facing the crossbar (2) is further from this side (4) in the floor of the undercut than the start of the undercut. The seat has an integrated projection (7) where it (1) faces the crossbar to reach with this (7) into the undercut. The undercut floor is radiused and projection (7) is shaped to conform on its side furthest from the seat to the shape of the undercut. The projection can be held in the undercut by a holding element (11). The crossbar preferably has two mutually spaced undercuts engaged by as many seat projections (7,7a). The crossbar comes in box section complete with tee groove (9) on its side furthest from the seat (1).
