Abstract: A passenger seat for a vehicle is mounted by an extendible stud assembly which includes a housing attached to the seat; and a movable plunger carried by the housing and including a locking stud adapted for engaging a locking track. The housing is constructed such that movement of the stud relative to the housing under an applied load causes deformation of the housing which resists the motion. This controlled motion of the locking stud allows a deck of the aircraft to deform under crash loads without imposing excessive loads on the passenger seat.
