Definitions

  • the invention relates to a height-adjustable backrest for seats, in particular vehicle seats, in particular for seats of road vehicles, and in particular for car seats.
  • the object of the invention is to demonstrate a height-adjustable backrest in which a shape of the backrest which is optimally adapted to the normal, anatomical course of the back or the spine is retained in each adjustment position.
  • a backrest is designed according to claim 1.
  • a vehicle seat with such a backrest is designed according to claim 8.
  • Fig. 1 shows the height-adjustable backrest in a simplified representation
  • FIG. 2 in a simplified representation and in plan view an inner support member of the
  • the backrest 2 is adjustable according to the double arrow A in height by a certain amount.
  • this consists of a vertical or inclined column 4 corresponding to the inclination of the backrest 2, which is provided in the middle of the backrest 2 and on which several support elements 5 are provided in succession in the longitudinal direction of the column.
  • Each support element 5 lies with its longitudinal extension transverse or radial to the longitudinal extension of the column 4, is held in the middle on the column 4 and guided axially displaceably on this column.
  • a sleeve-like guide element 6 is provided on the back of each support element 5, which is attached to the column 4.
  • the support elements 5 are convex on this rear side provided with the guide element 6 and curved concavely on the front side, which also faces the front side of the backrest 2. All support elements 5 in the illustrated embodiment continue to have the same length.
  • the support elements 5 each have a different distance from the column 4, which is achieved by different lengths of a web 7, which connects the respective guide element 6 to the center of the support element 5 on its convex side.
  • the support elements 5 are guided in a telescoping manner, that is to say the support elements 5 have tubular sections 8 in the embodiment shown, each above and below the respective support element 5 have a different cross-section, ie for example above the respective support element 5 an inner cross-section which is equal to the outer cross-section below the respective section element, so that the tubular sections 8 of all support elements 5 can interlock telescopically.
  • Resilient spacers 9 are provided on the column 4 between the support elements 5.
  • a corresponding spacer 9 is also provided between the lowermost support element 5 and a counter bearing on the column 4.
  • the spacers 9 prestress the supporting elements 5 into an upper position, which corresponds to the uppermost adjustment position of the adjustable backrest 2.
  • the uppermost support element can be actuated by a drive element, for example by a cable pull acting on the guide element 6 of the uppermost support element 5, which is indicated in FIG. 1 by the line 10 and is actuated by an actuator accommodated in the column 4, for example an electric drive 5 and with this also the underlying support elements 5 are each moved downwards against the action of the spacers 9, so as to increasingly move the backrest 2 into its lower adjustment position.
  • the usual upholstery of a vehicle backrest is applied to the support unit 5 formed by the support elements 5, but in such a way that the Height adjustment of the backrest 2 is not affected.
  • the outer covering of the backrest is preferably formed by an elastic or stretchable fabric.
  • the uppermost support element 5 naturally forms the top of the backrest with appropriate padding. With the uppermost support element 5, the headrest 1 1 is connected, so that this is automatically adjusted with the height adjustment of the backrest 2.
  • the headrest 1 1 also forms a space 12 which can accommodate the upper end of the column 4 when adjusting the backrest 2.
  • the training is further preferably made so that the individual support elements 5 against the action of a restoring force, for example, by the upholstery, the seat covering, by the elasticity of the interlocking pipe section 8 or by additional spring elements, for example springs passed through the pipe sections 8 is formed from its starting position, in which the support elements 5 are directed with their concave side toward the front of the seat, about the axis of the column 4 can be rotated so far that a person sitting in the vehicle seat 1 with a slight twisting of the backrest 2 can easily turn to the side or backwards.

  • the spacers are, for example, bodies made of a rubber-elastic material, for example made of elastic plastic. Steel springs are also suitable as spacers.
  • the lowest support element 5 is fixed in the embodiment shown, but at least connected to the column 4 in such a way that this support element cannot move axially on the column 4.
  • the column 4 is suitably pivotably provided at its lower end on a frame of the vehicle seat 1, while maintaining the functions customary in vehicle seats. Even if only four support elements are shown in FIG. 1, the backrest can have a higher number of such elements.
