#CMT# #/CMT# The frame has a lever (17) mounted in a mobile manner around an articulation axle (15) carried by a rigid armature (5), and extending parallel to a transverse axle (8) of a pivoting connection arm (7). The lever activates a mechanism constituting a cam (20), a transverse axle (21) and a projection (22), and disables a toothed sector (13) and a locking plate (14) at a height of the arm. The arm is instantaneously pivoted around the axle (8) in a direction such that the armature is brought back and lowered towards its position near a floor pan (12) of a passenger compartment. #CMT#USE : #/CMT# Retractable frame for a seat of a motor vehicle. #CMT#ADVANTAGE : #/CMT# The pivoting connection arm is instantaneously pivoted around the transverse axle in the direction such that the armature is brought back and lowered towards its position near the floor pan of the passenger compartment, thus increasing safety conditions in case of violent shock on the vehicle. The retractable frame is simple, reliable and robust. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a detailed side view of a retractable frame of a seat having main elements in a normal utilization position of the seat. 5 : Rigid armature 7 : Pivoting connection arm 8, 21 : Transverse axles 12 : Floor pan 13 : Toothed sector 14 : Locking plate 15 : Articulation axle 17 : Lever 20 : Cam 22 : Projection. |
