Vehicle seat

The innovation relates to a Pahrseugsit-z with a back part and an adjustable headrest arrangement carried by this, which is composed of an upwardly extending support rod which can be moved upwards and downwards relative to the back part and a headrest cushion arranged at its upper end, and at which to hold the stick in a preselected position from a number of relative positions to the back part, place a spring clip attached to this in a preselected notch from a view! engages along the support pins _L , 3 notches machined at a distance from one another.

.1 There is a need for a head-piece arrangement which is § relatively inexpensive to manufacture, has a long service life and is characterized by particular operational reliability.

It is an important goal of the innovation to have one with simple | Coats to create a vehicle seat Mf of a headrest arrangement which can be produced economically and which meets the requirements described in a particularly reliable manner.

In the case of a vehicle seat according to the innovation, it is provided that the notches are arranged along opposite sides of the support rod and that the spring clip with opposite sides End pieces each engage a corresponding notch of a preselectable pair of notches facing away from one another.

Further features, details and advantages of the innovation emerge from the following description of an embodiment example based on the drawing. It shows:

SIg, 1 is an oblique view of part of the rear frame a driver trained according to the fire and

Fig. 2 is a longitudinal sectional view on an enlarged scale the line H-II in Fig. 1.

According to the drawing is the back part of a vehicle seat from a reversed to reordered, U-shaped frame formed from U-profile. Between opposite legs 4 of the frame 2 is in the area below the horizontal Sahis part 6 is a cross member 8 made from TJ profile Elngesetst, which carries a driving bracket 10. These Is also made from Ü-Frofil. At their se

subsequent outer flanges 12 are fastened by means of a welded connection in a suitable manner on the front side of the cross member 8 so that the main wall of the guide bracket 10 runs parallel to this. From this it follows that the guide holder 10, in cooperation with the "front side or surface of the cross member 8, forms a guide with a rectangular cross-section in which a guide rod 14 is displaceably guided with a corresponding cross-sectional area. The support rod 1 ² I- extends upwards and penetrates a rectangular slot machined into the main wall of the right-hand part 6 of the frame 2. In order to additionally increase the rigidity of the arrangement, the support rod 14 is further guided through a rectangular slot machined into a guide plate 16, which is also the side walls of the horizontal frame part 6 and is arranged parallel to the main wall of the frame part 6.

In the lower area on the side edges of the support rod there is a number of notches hz \ i arranged in pairs, facing away from one another and along the support rod at a distance from one another. Notches 22 are provided. The main and side walls of the guide bracket 10 are enclosed by a spring clip 24 which is held in position near the outer surface of the guide bracket 10 by means of a hook tab 26. The hook-shaped or cranked tab 26 protrudes from the main wall of the Fahrunehalterrnig 10 forwards and upwards. The spring clip 24 is bent at each end first inward and then ivivder outward and thus has arcuately curved, inwardly directed lawns 28, which are each passed through a recess in a corresponding rare wall of the guide aging 10 and into the corresponding notches hzvi. Notches 22 of a pair of notches or notches on α he ütütsstange 14 engage. The feather cone 24 is advantageously made from spring wire.

The support bar is used to raise or lower the headrest 14 upwards or downwards relative to the rear runner 2 moved down to any of the discrete positions in which the lugs 28 of the spring clip 24 into the corresponding Hastening a pair of wires 22 intervene. Once the support rod 14 is retracted into one of these discrete positions, it is protected against unintentional movement by means of the spring clip 24 locked or secured up and down.

A V-like shape is expediently selected for each of the notches or ridges 22, the apex section of each Notch 22 for receiving a nose 2S of the spring clip 24 is arcuate. The side walls of each notch are at an angle, for example 90 degrees, relative to each other, so that the lugs 26 of the spring clip 24 can be released from the notches as soon as: to the high or low! set the headrest a force acting in the vertical direction is exerted on the support rod 14.

All of the claims, the description and the drawing features and advantages of the price increase, including constructive details and spatial arrangements, can be essential to the innovation both individually and in any combination.
