Motor vehicle e.g. commercial vehicle, has fixation unit with rigid transversal wire integrated to rear crosspiece by maneuvering control screw mounted on front side of base, where screw displaces hook between locking and release positions

摘要

#CMT# #/CMT# The vehicle has a fixation unit (34) for fixing a base (24) of a seat (4) on rear and front crosspieces (12, 14). The unit has a rigid transversal wire (36) integrated in a fixed manner to the crosspiece (12) by maneuvering a control screw (40) mounted on a front side (26) of the base. A hook (38) is movable with respect to the base between locking and release positions with respect to the wire. The screw displaces the hook between the two positions. A driving unit (42) articulating the hook has a longitudinal rod (58) with a threaded orifice receiving threaded body of the screw. #CMT#USE : #/CMT# Motor vehicle e.g. commercial vehicle. #CMT#ADVANTAGE : #/CMT# The rigid transversal wire is integrated in the fixed manner to the rear crosspiece by maneuvering the control screw mounted on the front side of the base, thus permitting the fixation unit to fix the base of the seat on the rear and front crosspieces in an ergonomic manner. The control screw is easy to operate due to a large free space between the seat and dashboard of the vehicle, and the operator does not have to intervene behind the seat in the space separating the seat and the partition. The rear crosspiece is locked in a simple and inexpensive manner. The mounting and dismounting of the seat is made in a rapid manner by operating four screws to fix the seat on the crosspieces. The hook is displaced only in the vertical direction, thus reducing the mechanical constraints of sizing of the hook. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a side view of a cab interior of a commercial vehicle. 4 : Seat 12 : Rear crosspiece 14 : Front crosspiece 24 : Base 26 : Front side 34 : Fixation unit 36 : Rigid transversal wire 38 : Hook 40 : Control screw 42 : Driving unit 58 : Longitudinal rod.
