Definitions
- Coupling device for a telescopically adjustable structure such as a headrest or the like.
- the invention relates to a coupling device for a telescopically adjustable structure such as a headrest or the like.
- Headrests for example of vehicle seats, are usually connected to the backrest of the vehicle seat with the aid of a connecting element and are adjustable in height.
- Known headrests of this type can normally be adjusted as desired in a height range of the order of 60 to 100 mm. That is especially so. often not sufficient for very large seat users.
- the invention has for its object to provide a coupling device of the type mentioned, which allows an enlarged telescopic adjustment of the structure.
- a coupling device of the type mentioned at the outset in that the structure has a first and a second body, and in that the coupling device is provided such that the first body together with the second body along a first linear guide between a basic position and a first extension position and from the first extension position only the second body relative to first body is linearly adjustable up to a maximum position.
- the coupling device according to the invention is designed in such a way that the adjustment of the second body with respect to the first body is made possible automatically, ie without the actuation of a special actuating element, from the first extension position in order to adjust the second body as desired up to a maximum position. At the same time, the first body is automatically held back in the first extension position.
- the first linear guide can have at least one stationary first rod, which is formed at its distal end section with a recess defining the first extension position, and the first body can have a spring-loaded slide forming the coupling device, which in the first extension position moves into the recess formed in the first rod engages.
- the first body can have at least one channel for linear guidance of an associated second rod of the second body, and the second rod can be formed at its distal end section with a recess for the slide.
- Said slide is therefore expediently provided transversely to the first and second rods and is provided in the first body such that it can be adjusted transversely to the first and second rods in order to engage either in the recess on the distal end section of the first rod or in the recess on the distal end section of the second rod .
- the second rod may be formed with an inclined surface at its distal end, and the slider may be formed with a system section when shortening the structure from the maximum position back to the first
- Extension position on the inclined surface can be adjusted such that the slide is released from the recess in the first rod and at the same time engages in the recess in the second rod and connects the second body to the first body. Through this connection, the second body can then be adjusted back together with the first body into the basic position from the first extension position back to the basic position.
- the coupling device according to the invention is simple and has only a few individual parts, which is advantageous from an assembly point of view.
- the figure shows sections of a backrest 10 of a vehicle seat 12.
- the backrest 10 is formed with a recess 16 which is used to hold a
- Headrest 18 is provided, the headrest 18 being combined with an intermediate body 24.
- the intermediate body 24 forms a first body and the headrest 18 forms a second body.
- a base device 22 fixed to the seat or backrest which has a base element 30 and side elements 32 which project laterally from the base element 30 having . Only one of these two side elements 32 is shown in the figure. Each of the two side elements 32 is formed with a guide slot 34. Rod-shaped guide elements 36, which are guided in the corresponding guide slots 34, project laterally from the intermediate body 24.
- first rods 38 From the base element 30 of the seat-fixed base device 22 there are also two first rods 38 oriented parallel to one another, of which only one of the two rods 38 is also shown in the figure.
- the intermediate body 24 is formed with two first channels 40, into which the first rods 38 extend without play.
- a first linear guide is determined by the first rods 38 and the first channels 40, along which the intermediate body 24 forming the first body together with the headrest 18 forming the second body can be adjusted from the basic position sunk into the recess 16 to a first elevated extension position.
- the headrest 18 forming the second body has two parallel rods 42 oriented parallel to one another, which project downward from the headrest 18 and which extend into associated second channels 44 in the intermediate body 24.
- the second channels 44 are formed in the intermediate body 24 at a distance from the first channels 40 to the side of these.
- the slide 50 is provided in the intermediate body 24 transversely to the first rod 38 and the second rod 42 and is arranged to be linearly movable.
- the slider 50 is forced against the first rod 38 by means of a spring element 54 which is arranged in a recess in the intermediate body 24.
- a sleeve 56 is fixed on the upper side, which enables a gradual adjustment of the headrest 18 with respect to the intermediate body 24 from the first extension position to the maximum position.
- the second rod 42 is formed on its underside, ie on its distal end section 58, with a recess 60 which has a greater clear height in the axial direction than the thickness of the slide 50.
- the recess 60 serves to receive the slide 50 of the coupling device 52 when the headrest 18 is moved from an extension position located above the first extension position against the intermediate body 24 defined in the first extension position.
- the inclined surface 62 formed on the distal end section 58 of the second rod 42 comes into contact with a contact section 64 of the slide 50 to abut, so that the slide 50 is moved out of the recess 48 in the distal end section 46 of the first rod 38 and engages in the recess 60 at the distal end section 58 of the second rod 42.
- the headrest 18 can then be moved together with the intermediate body 24 into the recess 16 in the backrest 10 of the vehicle seat 12.
