Definitions

  • THE PRESENT INVENTION relates to a head-rest, and more particularly relates to a head-rest for use in a motor vehicle.
  • a head-rest On a seat in a motor vehicle.
  • a principal function of the head-rest is to prevent the head of the occupant moving rearwardly, relative to the torso of the occupant, in the event that a rear impact should arise.
  • the head-rest prevents the head of an occupant of the vehicle moving in an undesirable way when the occupant moves back into the seat after being restrained by a seat-belt and/or air-bag, following a frontal impact.
  • a head-rest may also find an additional use, especially by a passenger in a motor vehicle, where the head-rest may provide support for the head of the passenger, especially if the passenger wishes to rest or sleep.
  • a typical head-rest only provides a relatively small area upon which to rest the head.
  • One reason for this is to enable rear seat passengers to enjoy a forward view.
  • elements which move from a retracted position to an extended position, in order to provide more support.
  • US-A-4 ,205, 878 discloses an arrangement in which two elements are provided, one located on each side of the central part of the head-rest, the elements being movable axially, that is to say in a direction extending towards the front of the seat, in order to provide improved support.
  • the remaining area between the two elements, when they are in the forwardly extended position is relatively small.
  • the present invention seeks to provide an improved head-rest.
  • a head-rest for a motor vehicle seat the head-rest defining a front face adapted to support the head of an occupant of the seat, and side parts located on either side of the front face, the head-rest having two extendable elements, each adapted to move from a retracted position to an extending position, the extendable elements being adapted to move, with a sliding motion, from the retracted position through the side parts of the head-rest to an extended position in which the elements extend laterally relative to the head-rest and forwardly relatively to the head-rest.
  • each extendable element comprises means adapted to engage a rail defined within the head-rest, each element being movable in a slidable manner along the rail.
  • the rail is of arcuate form.
  • the rail comprises two opposed arcuate recesses, and each movable element has an arcuate plate, the opposed edges of which are received within the opposed recesses.
  • the recesses are formed in the upper and lower walls of a substantially hollow tubular housing that extends transversely of the head-rest.
  • the front face of each extendable element is upholstered.
  • FIGURE 1 is a perspective view of a head-rest for a seat in a motor vehicle in a first condition

  • FIGURE 3 is a view showing part of the head-rest of Figures 1 and 2 (with parts being cut away for the sake of clarity of illustration) illustrating the interior of the head-rest,
  • FIGURE 4A is a horizontal sectional view of the head-rest in the condition of Figure 1, and
  • FIGURE 4B is a horizontal sectional view of the head-rest in the condition of Figure 2.
  • a head-rest 1 to be mounted on a vehicle seat presents a front face 2 which may be constituted by fabric, or by a thin layer of plastic material, which may simulate leather, or by real leather, which is located in front of interior padding.
  • the head-rest presents two side faces 3,3*.
  • a central region of each side face 3,3' is formed by one end 4 of an extendable element 5,6 which can be moved from a retracted position, as shown in Figure 1, in which the extendable elements 5,6 are totally retained within the head-rest 1, to a position as shown in Figure 2 in which the extendable elements 5,6 extend laterally outwardly and forwardly from the side faces 3,3' of the head-rest 1.
  • the extendable elements are movable manually from the retracted position as shown in Figure 1 to the extended position shown in Figure 2.
  • the forwardly directed face 7,8 of each of the extendable elements 5,6 may be covered with fabric, or a layer of plastic material, which may simulate leather, or may be covered with real leather, and padding is located behind the fabric or the layer of plastic so that the front face 7,8 of each of the extendable elements 5,6 forms a comfortable surface against which the occupant of the seat may rest his head.
  • the front face 2 of the head-rest 1 is illustrated and comprises, as mentioned above, either fabric or a layer of a plastic material, or a layer of leather.
  • a support element 10 Contained within the head-rest is a support element 10, in the form of a hollow tubular housing, which extends transversely of the head-rest.
  • the support element 10 has a front, substantially vertical wall 11.
  • the front wall 11 is a rigid wall having an outwardly curving form, and is separated from the front face 2 of the head-rest by padding.

  • the support element 10 also includes a lower wall 14 which inter-connects the front wall 11 and the rear wall 12, and an upper wall 15 which also inter-connects the front wall 11 and the rear wall 12.
  • the lower wall 14 has defined therein two arcuate grooves, 16,17, located at respective opposed ends of the support element 10 and extending generally axially of the support element.
  • the arcuate grooves are symmetrically arranged, and lie on a common arc.
  • the upper wall 15 also has to arcuate grooves formed therein, only one of which, 18, is visible in Figure 3.
  • the arcuate grooves in the upper wall 15 overlie the arcuate grooves 16,17 in the lower wall.
  • the arcuate grooves as described above, define rails which support the extendable elements 6 and 7.
  • each of the extendable elements 5 and 6 comprise an inner metal core 20.
  • the inner metal core defines a vertical arcuate plate 21.
  • the radius of curvature of the arcuate plate is the same as the radius of curvature of the arcuate grooves.
  • the upper and lower edges of the arcuate plate 21 are received within the arcuate grooves 16,17,18, so that each metal core 20 may slide along the rail defined by the grooves .
  • Each metal core also defines an axially extending end piece 23 which extends axially of the seat to which the head-rest is fitted and substantially transversely to the arcuate plate 21.
  • the metal core is provided with an outer covering 24 formed of fabric or a layer of plastic which may simulate leather, or a layer of real leather.
  • the outer covering 24 lies adjacent the rear surface of the arcuate plate 21 and then passes adjacent to the exterior of the end piece 23.
  • the fabric or layer of plastic or layer of leather 24 then extends in front of the metal core 20 and is separated therefrom by means of padding 25. This part of the fabric or layer of plastic or layer of leather thus provides an upholstered front face 7,8 for the extendable elements.
  • the extendable elements are moved from the retracted position as shown in Figure 1 and Figure 4A, by manually grasping the exposed end parts of the extendable elements and applying an appropriate force, causing the elements to slide, in an arcuate manner, along the rails defined by the arcuate recesses 16,17,18.
  • Figure 4B when the extendable elements are in the extended position, each element presents a relatively comfortable upholstered front face 7,8, which effectively forms a forwardly and laterally extending projection of the front face 2 of the head-rest.
  • the head-rest provides a substantial degree of comfort to a person who wishes to use the head-rest as a support for the head whilst sleeping.
  • the extendable elements may be mechanically interconnected, so that when one of the elements is grasped and moved, the other element simultaneously executes an eguivalent movement.
  • Means such as a motor driving pinions which engages rocks carried by each extendable element, to drive the extendable elements between the extended and retracted positions.

Abstract

Cette invention se rapporte à un appuie-tête (1) pour un siège de véhicule à moteur, qui présente une face frontale (2) et deux faces latérales (3, 3'). Cet appuie-tête comprend deux éléments extensibles (5, 6), qui, au départ, sont totalement rétractés dans l'appuie-tête mais qui sont conçus pour se déplacer, par un mouvement coulissant, jusqu'à occuper une position déployée. Ces éléments (5, 6) se déploient alors latéralement par rapport à l'appuie-tête et vers l'avant par rapport à l'appuie-tête, formant ainsi un soutien supplémentaire pour la tête de la personne occupant le siège.
