Electric headrests

The invention relates to headrests, in particular for motor vehicles.

Headrests for car seats are manually adjustable using their support rods. When no one is sitting in the back seats, they obstruct the driver's view of the rear through the rear window and therefore have to be laboriously removed or folded down by hand by the driver and then reattached when someone sits down - something that is often dangerously forgotten. Headrests also interfere with folding the rear seats in order to load the trunk.

The invention consists in providing a headrest which does not have these disadvantages.

The solution according to the invention is to move conventional headrests out of the field of vision, i.e. below the rear window height, using a corresponding commercially known electronic mechanism or an electric motor which is integrated in the seat, automatically triggered by a commercially known seat occupancy sensor which extends or folds up the supports when someone sits down and retracts or folds them down again when the person leaves the seat, so that the view to the rear is cleared, or such an electric mechanism can be operated manually by means of a switch.

In one form of the invention, gears driven by the electric motor engage the notches of the headrest support rods in order to lower them into a recess in the back seat and raise them again. In another variant, the electric motor-driven gears engage gear hinges of the headrest support rods in order to adjust their angle position or to bring them to a horizontal level or to fold them flat backwards so that the field of vision is also clear here.

The invention is described below using two embodiments as examples, with reference to the accompanying drawings. They show in schematic representation:

Fig. 1 - side view of a first embodiment of the invention
Fig. 2 - a second embodiment in side view

In the figures, a headrest (1) is connected to a seat (10) by means of support rods (2). An electric motor or electronic mechanism (8) rotates a gear (7) which in Fig. 1 engages in notches (4) on the support rod (2) to change the position of the supports (1) and to lower them into a recess in the seat back (5). Additional support devices for the support rods (6) fit into a corresponding recess in the headrests (3). A recess is also provided in the seat back (9) for the support rods (2).

In Fig. 2, the electric motor (8) rotates a gear (7) which is connected to the
The gear hinge (7) (2) which is firmly connected to the holding rods (2) engages and thus adjusts the angular position of the headrests (1) and can tilt the latter flat backwards, i.e. bring it into a horizontal position.

In both forms of the invention, a cable (13) supplies electricity to operate the mechanism or electric motor. This is also connected via a cable (11) to a suitable switch (12) or a commercially known seat occupancy detection sensor (12) to change the position of the headrests (1) accordingly.

Claims (1)

Headrest ( 1 ), in particular that of a passenger car, characterized in that it can be adjusted, folded over or sunk into a recess in the seat back ( 5 ) or pushed up and down by means of a suitably suitable and commercially known electric motor or electronic mechanism ( 8 ) which can be activated manually by means of a switch ( 12 ) or automatically by means of a seat occupancy detection sensor ( 12 ).
