The invention relates to a suspension device, in particular for a vehicle seat, comprising an upper suspension part and a lower suspension part, which can be connected to one another by a first swivelling connector and a second swivelling connector, wherein a first spring unit can be connected in a first end region on the one hand by means of an adjusting device to the first swivelling connector and can be connected in a second end region on the other hand to the lower suspension part, wherein by means of the adjusting device the position of the first spring unit can be adjusted in order to adjust the spring force and the spring rate of the suspension device.

Suspension device

The invention relates to a vehicle seat () with a framework () for fastening the vehicle seat () to a vehicle body (), with a seat part (), with a backrest () and with a head support () comprising a head support suspension (), in which the seat part () and the backrest () are arranged on the framework (), in which the head support suspension () is formed by the framework () or is fastened to the framework () and in which the head support suspension () has a suspension part () on the side towards the framework and a suspension part () on the side towards the backrest, wherein the suspension part () on the side towards the backrest is arranged outside the backrest ().

Disclosed is a vehicle seat with seat part, backrest, belt restraining system and support structure supporting the seat part and backrest. Belt restraining system comprises belt reversal means and belt lock. Belt reversal means is positioned in an upper corner region of the backrest and belt lock positioned in seat area of seat part. Support structure has asymmetrical framework with main force braces extending substantially vertically. Main force braces converge in junction region and underside of support structure a first, second and third one of main force braces is arranged on the side towards the junction region as a thrust brace guided forwards as far as a front foot; on the side towards the junction region as a tension brace at the rear guided as far as a first rear foot; tension/thrust brace at the rear guided as far as a further rear foot.

Belt fastening on the rear main tube of the backrest, ideally on the rear foot situated at the bottom

The invention concerns a spring system for use in vehicles for adjustment of the suspension characteristics, comprising at least one spring element to provide a spring force, an upper and a lower arrangement area to receive forces, a scissors-type frame arranged between the upper and the lower arrangement area for coupling the spring element with at least one force acting on one of the arrangement areas. According to the invention the spring element is coupled with a deflection means to influence the spring force and between the deflection means and a segment of the scissors-type frame an active connection can be created to transmit forces.

Change of spring force by means of levers

The invention relates to a vehicle seat with a seat part, with a backrest and with a support structure for supporting the seat part as well as the backrest, in which the support structure is capable of being fastened to a bodywork component and in which forces acting upon the vehicle seat by means of the support structure are capable of being introduced into the bodywork component, and in which the support structure has an asymmetrical framework with main force braces extending substantially vertically.

Vehicle seat with a support structure

A control device is shown to reduce a vibration movement of a device vibrating under spring force with at least two mobile parts vibrating in relation to each other, wherein the parts are connected together by means of mobile connecting arms, at least one of the connecting arms is connected with a first spring element end of at least one spring element and between the parts is arranged at least one damping element.

Control device to reduce vibration movement on a device vibrating under spring force

To be able to produce a scissors-type frame of a vehicle seat in a quick and easy manner, the present invention is directed to a scissors-type frame for a vehicle seat, in particular for a motor vehicle seat, comprising a first scissors element and a second scissors element, wherein the scissors-type frame is height-adjustable by means of the two scissors elements, and wherein the scissors-type frame is characterized in that one of the two scissors elements passes through the other of the two scissors elements.

Scissors-type frame for a vehicle seat and method for producing a substructure of a vehicle seat

Spring-mounted vibration system to reduce vibration with a first spring-mounted part and a second spring-mounted part, wherein the first spring-mounted part and the second spring-mounted part can oscillate relative to each in at least one vibration direction and at least one of the spring-mounted parts can be exposed to a return force on a vibration movement. A control unit is arranged with at least one travel linkage which is connected with at least one of the spring-mounted parts and in which is arranged displaceably at least one guide element connected with a spring element generating the return force and/or the other spring-mounted part.

Spring-mounted vibration system to reduce vibration

What is shown is a vehicle seat having parts for carrying out a vibration movement in the height direction, with the parts comprising the following:

Vehicle seat with vibratory motion in the height direction

A vehicle seat includes a height-adjustable seat frame which has at least two seat frame parts which can be moved relative to one another and at least one gas spring arranged between the seat frame parts for height adjustment purposes. The seat includes a control device that acts upon the gas spring and includes a valve device attached to a first seat frame part and has control valves for actuating gas flows for the gas spring. A control link on a second frame part actuates the control valves, so that a predefinable height of the vehicle seat is ensured regardless of a weight load on the vehicle seat. Movement of the control link relative to the second seat frame part brings about a height adjustment of the vehicle seat.
