摘要

#CMT# #/CMT# The head-restraint has a bar (7) fixed in a backrest of a seat, and a structure carrying a flexible cushion (2). A locking elastic unit (5) comprises two contact portions (5b, 5d). The structure is movably mounted with respect to the bar for controlling unlocking of the heat-restraint between locking and unlocking positions in which the portions prevent and authorize the movement of the structure with respect to the bar according to a translation along a longitudinal axis of the bar, respectively. #CMT#USE : #/CMT# Used for a seat of a motor vehicle (claimed). #CMT#ADVANTAGE : #/CMT# The structure carrying the flexible cushion can be moved for unlocking the head-restraint, thus eliminating the need for a control knob for unlocking the head-restraint and allowing a user to easily see that the head-restraint is unlocked. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a side view of an internal structure of a head-restraint of a seat of a motor vehicle. 1 : Head-restraint 2 : Flexible cushion 5 : Locking elastic unit 5b, 5d : Contact portions 7 : Bar.
