Embodiment Construction

[0042] figure 1 Shown is a seat 104 of a motor vehicle having a seat part for accommodating an occupant 101 of the seat and a backrest 103 supporting a headrest 10 via two parallel pins 1a, 1b along The longitudinal axis of the pin extends. In the present application, the pins extend along or close to the direction of the first direction Z, relatively close to the vertical direction in the normal position of using the seat.

[0043] Said seat may be a driver's seat or a front passenger's seat; application of the invention to rear seats or seats of trucks, vans, utility vehicles or off-road vehicles is not excluded.

[0044] In the example shown, the pins 1a, 1b are inserted in a relatively conventional manner into two sheaths (not shown) of the backrest 103, said pins being extended by uprights 11, 12 extending upwards in the Z-direction, by The connection is via an upper connection 13 , also called a beam. This forms the supporting structure 1 of the headrest in the sense ...

Abstract

Adjustable headrest for a motor vehicle seat, comprising a support structure (1) fixed to the backrest, a body (8) comprising a front shell (7) and a rear shell (6) having a The front surface (70) contacted by the head of the user of the chair is movable relative to the support structure in the fore-aft direction marked X over the total travel distance (CT) The distance is formed by a first travel part (C1) provided by the translational movement enabled by the mounting of the body relative to the support structure, and a second travel part (C2), the front The position of the shell relative to the rear shell remains substantially constant; the second stroke portion ( C2 ) is provided by the translational movement enabled by the mounting of the front shell relative to the rear shell.

Description

technical field [0001] The invention relates to head restraints for motor vehicle seats. [0002] In particular, the present invention relates primarily to a head restraint, the position of the front surface of which is adjustable in a longitudinal direction (marked X) (near the longitudinal direction of the vehicle) and optionally adjustable in a substantially vertical direction (marked Z). Background technique [0003] When using a single-volume ("one-piece") head restraint, the adjustment travel along X is limited by the compatibility of internal mechanisms and support structures, as well as stylistic constraints on the head restraint. [0004] In order to increase the adjustment travel along X, the trend is towards "dual volume" solutions, in which the front cushion of the headrest can be moved relative to the base structure in the central and rear area of ​​the headrest. [0005] Such a headrest is known from document FR2979867 originating from the applicant. Another ...
