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

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

The invention relates to a vehicle seat having a backrest and a seat surface device that forms a seat surface and that is provided with a pad cover, in particular an outer pad cover, wherein the seat depth of the seat surface is adjustable. A seat depth adjustment device facilitates seat depth adjustment, the seat depth adjustment device including a first deflection device for deflecting the seat pad cover in the end region of the seat surface remote from the backrest, a flexible part that is coupled to the pad cover, and at least one second deflection device for deflecting the flexible part, the second deflection device being arranged at a distance from the first deflection device.

The invention relates to a vehicle seat with a backrest () and a seat part (), wherein the seat part () can be displaced in the forward and backward direction () with respect to a base frame () and the backrest () has a lumbar spine region () which can be deformed in the forward and backward direction (), wherein a rocker-like element () is provided which is arranged in the lumbar spine region () such that it can pivot about a horizontally running pivot axle (), said rocker-like element extending at least partially along the longitudinal direction of the backrest, wherein the pivot axle () can be displaced together with the seat part () in the forward and backward direction () and a pivotable section () of the rocker-like element () is attached to the base frame () in a backrest region of the base frame ().

Vehicle seat with a deformable backrest

A roller guide for adjustable vehicle seats. The roller guide includes at least one guide rail which is at least partially open at the side and at least two rollers which roll in the guide rail and are connected to the vehicle seat via at least one axle. At least one of the rollers is shaped like a cone or a truncated cone. The cone surface can roll as the bearing surface of the roller moves along an inner wall of the guide rail. The inner wall being arranged at an angle with respect to the longitudinal axis of the axle.

Roller guide for adjustable vehicle seats

A seat with a backrest and sitting surface, in particular for motor vehicles, wherein the backrest comprises a backrest frame and, disposed between it, elements forming an S-shaped backrest with a shoulder area that can be reconfigured in the forwards and backwards directions, and a lumbar spine area that can be reconfigured in the forwards and backwards directions, wherein the elements are swivel-mounted to rotate about an imaginary or real axis extending horizontally between the shoulder and lumbar spine areas and running through the backrest frame or parallel with it in such a way that, without changing an existing inclination setting of the backrest relative to the sitting surface, a reconfiguration of the lumbar area and/or the shoulder area in the forwards direction can be made automatically by reconfiguring the shoulder area and/or the lumbar area in the backwards direction.

Seat with ergomechanics

A vehicle seat with a backrest and a seat part. The backrest includes a backrest frame and S-shaped rod elements arranged therebetween so as to form an S-shaped backrest having a shoulder region which can be deformed in the forward and backward direction and a lumbar spine region which can be deformed in the forward and backward direction. The rod elements, which extend in the longitudinal direction of the backrest, are pivotably mounted by their lower and upper ends on the backrest frame such that they can be pivoted about an imaginary axis which extends in the longitudinal direction of the backrest. The rod elements are mounted on the backrest frame such that they can be displaced in the longitudinal direction of the backrest.

Vehicle seat with a deformable S-shaped backrest

A vehicle seat comprises a seat squab supported on a base structure, and a spring arrangement for weight adjustment, the spring arrangement being connected to a weight adjustment actuating device. Associated with the actuating device is a level indicator device for indicating adjustment of the seat squab to the seat squab level which optimally corresponds to the weight of the respective seat occupant, in relation to the spring travel of the seat squab. The level indicator device and the actuating device are provided at least substantially centrally at the front edge of the seat squab for optimum actuability and adjustability.

Vehicle seat

A sprung vehicle seat has a base member and a top member, and a scissor support assembly operatively disposed therebetween. The scissor support assembly comprises first and second pivotably interconnected scissor levers. Secured to the first scissor levers is a sliding guide in the form of a plate member which is oriented in the longitudinal direction of the seat. A spring member bears against the sliding guide and the top member and is displaceable in the longitudinal direction of the seat for the purposes of weight adjustment of the seat.

Sprung vehicle seat

Described is a vehicle seat having a safety belt which can be extended from a belt retractor. The belt retractor is mounted to one side of the vehicle seat. A belt end portion which projects from the belt retractor is provided with a spring hook means. An engagement element for retainingly receiving the spring hook means is disposed at the second side of the vehicle seat.

Vehicle seat with safety belt assembly

A driver restraint device is provided for an industrial truck which has a driver's seat. The driver restraint device has a belt (4) and a belt buckle (8). A closing latch (5) which is connected to the belt (4) can be fastened to the belt buckle (8). The belt (4) can be automatically retracted by means of a retractor (9), whereby when the belt (4) is retracted, the closing latch (5) is in a defined inoperative position. The belt (4) is fastened to a mounting device which is connected to the driver's seat so that when the closing latch (5) is in the defined inoperative position, it is located in front of a vertical transverse plane (12) which divides the seat surface (1) of the driver's seat in the middle. In an additional embodiment of the invention, the belt buckle (8) is fastened to a mounting device which is connected to the driver's seat so that the belt buckle (8) is located in front of a vertical transverse plane (12) which divides the seat surface (1) of the driver's seat in the middle. In one configuration of the invention, the closing latch (5) in the defined inoperative position is at some distance above the horizontal plane defined by a seat surface (1) of the driver's seat.

Driver restraint device for an industrial truck

A driver restraint device for an industrial truck with a driver's seat has at least one restraining guard, for which an inoperative position and a restraining position are provided. During operation of the industrial truck, the restraining guard is in the restraining position, whereby it can be moved toward an inoperative position against a bias force. The restraining guard can be locked in position by a tripping device which detects a tipping of the industrial truck.
