摘要

#CMT# #/CMT# The seat (1) has a retracting system (7) comprising articulation devices (9, 11) for permitting to fold a backrest (3) on a base (5) and to retract the folded seat in a cavity (19), respectively. The system includes an assistance device (15) for assisting the articulation device (11) in order to retract and extract the seat with respect to the cavity. The assistance device includes a mechanical transmission unit pivoting between the base and a shock absorber unit to permit the assistance device to operate with respect to the seat. #CMT#USE : #/CMT# Seat for a motor vehicle (claimed). #CMT#ADVANTAGE : #/CMT# The seat utilizes a single assistance device to dampen acceleration of the movement of the seat by weight of the seat during the retraction of the seat in the cavity and to provide a thrust force during the extraction of the seat from the cavity in order to reduce efforts provided by a user for handling the seat during the retraction and extraction of the seat. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view illustrating a retracting movement of seat in a position. 1 : Seat 3 : Backrest 5 : Base 7 : Retracting system 9, 11 : Articulation devices 15 : Assistance device 19 : Cavity 43 : Mechanical transmission unit.
