1 84711 Swivel device for turning the vehicle seat

The invention relates to a pivoting device according to the preamble of claim 1 for pivoting a vehicle seat.

In the past, a number of different pivoting devices have been developed between the floor of the vehicle and the seat, by means of which the seat can be pivoted between a forward driving position and a position towards the vehicle door intended to facilitate exiting or getting into the vehicle. Such devices are subject to high demands in terms of operational safety, strength and road safety.

In addition, they should be space-saving so that they can be easily placed in all possible vehicle types. In particular, such devices are suitable for assisting persons with reduced mobility in getting in or out of the car 20.

The inventions disclosed in Swedish publication 445321, German application 2545742 and Finnish publication 76740 are unsatisfactory in operation. Em. the biggest problem with the devices is its limited movement, because the swivel joint is fixed in all devices. As a result, when the seat is turned, it must be slid along its rails at the same time, otherwise turning is impossible when the side of the seat 30 collides with the center console. Another problem is the high height of the devices, which makes it difficult to place them in different vehicles.

The turning device according to the invention provides a decisive improvement over the above-mentioned drawbacks.

To achieve this, the invention is mainly characterized by what is set forth in the characterizing part of claim 1.

The invention will now be described in more detail with reference to the accompanying drawings, in which

Fig. 1 shows the turning device according to the invention yl-5 from the ear, seen in a direction perpendicular to the plates,

Fig. 2 shows the transfer groove of the device seen from the pivot joint in the plane direction of the plates, and 10

Figure 3 shows a support member of the device, which at the same time acts as a stop in both directions, seen in the plane direction of the plates.

Thus, Figure 1 shows a turning device according to the invention seen directly from above. The turning device comprises two plates spaced at a constant distance from each other, the upper plate 1 and the lower plate 2. The plates 1, 2 are made in particular of a metal plate. The plates are fastened to each other by means of joints in the transfer groove 3, so that the upper plate 1 can be moved by the length of the transfer groove 3 in an arbitrary amount with respect to the lower plate 2.

The vehicle seat is attached to the upper plate 1 in a suitable manner. In the position shown in Figure 1, the upper plate 1 is turned to a position where the driver leaves the seat with the direction of travel of the vehicle indicated by arrow A. In the driving position, the upper plate 1 overlaps with the lower plate 2.

Between the plates 1 and 2, rolling members 4 are arranged at suitable intervals, which keep the distance between the plates 1 and 2 constant and make the movement of the plate 1 on the plate 2 sensitive. The winding members can be of any known type 35.

The turning device according to the invention also preferably comprises a support member 5, the function of which is twofold.

3,84711

First, the support member 5 is made of a metal tube or profile that is highly resistant to bending. Profii liter is well suited for the purpose. The other end of the support member is fixedly attached to the lower plate 2 by means of its hook-like end 5. However, the main part of the support member 5 is located on the upper plate 1, passing at a substantially constant distance therefrom. The hook-like end of the support member 5, which pivots around the edge of the plate 2, forms a natural stop for turning the plate 1 to the driving position.

10

In order for the support member to indeed act as a support member of the plate 1, it is provided with its lower surface facing the plate 1, also with rolling members 4 supporting the plate 1 from its upper surface when the plate is turned far to the exit position. In this case, the plate 1 naturally tends to bend under the influence of weight, with the supporting rolling rollers 41 and 42 acting as torsion support points. The outermost end of the part of the support member 5 on the plate 1, which in Fig. 1 is at the plate 1, resists the rising of said angle 20 of the plate and supports the plate 1 from above.

A stop may be suitably provided at the outer end of the support member 5 in co-operation with a stop on the upper surface of the plate 1 to stop the upper plate 1 so that it cannot pivot over its extreme point in the exit position given to it in each case.

The device according to the invention can be provided in a conventional manner with a locking device 6 by means of which the seat 30 is stabilized in place in the driving position. The folded-out seat can again be locked in place with, for example, an eccentric locking device 7, which locking devices are shown in the figures only by way of example, as they do not form part of the present invention.
