FR2903354A1 - Motor vehicle`s interior lift gate trim, has acoustic absorption cavities equipped with thin structure integrated with functional unit, and pierced rush arranged in reception groove to form peripheral completion - Google Patents

Abstract

The trim has an acoustic absorption cavities (2) equipped with a thin structure (1) integrated with functional unit (7) that are made of a handle (8) and a door fixation hook (9). A reverse side (3) of the structure is associated with a layer of a porous acoustic absorption material. A face side (4) of the structure is associated with a porous material finish layer. The absorption layer is arranged with respect to the finish layer in the cavities. A pierced rush is arranged in a reception groove that receives a periphery of the finish layer to form peripheral completion.

Description

The invention relates to a headrest of a motor vehicle seat. II

  It is known to make a headrest of a motor vehicle, said headrest comprising a body of elastic flexible material, in particular based on foam, comprising a front face of support of the head. When the passenger wishes to improve the timing of his head, especially for sleeping, a headrest as described above is unsatisfactory, this due to the slightly concave geometry of the front face. The proposed head restraints 10 to be convertible into sleep use are obtained by means of complex arrangements, such as the addition of lateral support members or the neck. The invention aims to overcome this disadvantage by providing a headrest 15 convertible sleep configuration, and this by a simple arrangement not implementing complex support members. For this purpose, the invention provides a motor vehicle seat headrest, said headrest comprising a body of elastic flexible material comprising a front face and a rear face, said headrest further comprising at least one device reversible compression of a predefined part of said body by bringing a predefined area of said front face towards said rear face.

In this way, a hollow is created in the front face, which allows a multipoint support of the passenger's head, and thus an improved setting of his head. The device being reversible, the user can return the headrest in a hollow-free configuration. In this description, the positioning terms in the space (front, rear, longitudinal, lateral, ...) are taken with reference to the headrest disposed in the vehicle.

Further features and advantages of the invention will become apparent from the following description with reference to the accompanying figures, in which: FIG. 1 is a schematic side section (1a) and a top view (1b) of a 5 headrest according to one embodiment of the invention, the headrest not being in sleep configuration, • Figure 2 is a schematic side section (2a) and high (2b) of a support head according to the embodiment of Figure 1, the headrest being in sleep configuration.

Referring to the figures, a headrest 1 of a motor vehicle seat is now described, said headrest comprising a body 2 made of elastic flexible material such as a foam, comprising a front face 3 and a rear face 10, said headrest further comprising at least one device 4 for reversibly compressing a predefined part 11 of said body by bringing a predefined area 7 of said front face towards said rear face. When the return device 4 is activated, it creates a recess 5 in the front face 3, which allows a multipoint support of the passenger's head, and thus an improved setting of his head. According to the embodiment shown, the device 4 comprises an anchoring means 6 of the zone 7 associated with one end of a cable 8, said cable traversing in free sliding and longitudinally at least a part of the thickness of the support head 1, the other end of said cable being associated with a winding means 9 for reversible traction of said anchoring means to the rear.

According to the embodiment shown, the anchoring means 6 is located substantially in the center of the front face 3.

According to one embodiment, the winding means 4 is arranged to make it possible to arrange the anchoring means 6 in a plurality of longitudinal positions, so as to optimize the adjustment of the comfort according to the user, for example at means of a serrated wheel system. According to an embodiment not shown, the headrest 1 may comprise at least two devices 4, said devices comprising a common winding means 9 for carrying out the winding by a single maneuver.

Claims (5)

  Headrest (1) of a motor vehicle seat, said headrest comprising a body (2) of elastic flexible material comprising a front face (3) and a rear face (10), said headrest being characterized in it further comprises at least one device (4) for reversibly compressing a predefined part (11) of said body by bringing a predefined area (7) of said front face towards said rear face.   2. headrest according to claim 1, the device (4) comprising an anchoring means (6) of the zone (7) associated with one end of a cable (8), said cable traversing freely sliding and longitudinally at least a portion of the thickness of said headrest, the other end of said cable being associated with a winding means (9) allowing reversible traction of said anchoring means to the rear.   3. Headrest according to one of claims 1 or 2, the anchoring means (6) being located substantially in the center of the front face (3).   4. Headrest according to any one of claims 1 to 3, the winding means (9) being arranged to allow to arrange the anchoring means (6) in a plurality of longitudinal positions. 25   The headrest according to any one of claims 1 to 4, said headrest comprising at least two devices (4), said devices comprising a common winding means (9).
