Definitions
- the present invention relates to a vehicle seat in which the backrest can be rotated about an axis of rotation from a use position into a storage position.
- Vehicle seats of this type are present in a large number of vehicles and are accordingly known from the prior art. Often these vehicles have a drive that performs the rotation from the use and storage position. According to the prior art, these drives must have a comparatively strong torque because they have to overcome the torques due to their own weight when the backrest is rotated. Furthermore, these drives must be self-locking in order to hold the backrest in the respective position. In particular due to the comparatively strong torque, this mechanism poses a hazard. For example, people or objects can get caught. Furthermore, it is possible that the seat back remains in an undesirable intermediate position, for example due to the failure of the drive, and / or the backrest can no longer be moved from one of the end positions due to a failure of the drive.
- the seat according to the invention is simple and inexpensive to manufacture. For example, according to the prior art, wobble fittings previously used can be replaced by simple, inexpensive fittings, without there being a safety risk for the vehicle occupants or the transported material.
- the vehicle seat has a means for balancing the backrest. Balancing in the sense of the invention means that the means at least largely compensates for the moments resulting from the weight of the backrest during rotation by means of a corresponding counter-torque. This counter moment can be compensated for by a spring or a weight with an appropriate lever.
- the mechanism is preferably designed so that only minimal actuating forces are required for the movement in each phase of the occupancy process of the seat between the end positions. Accordingly, the tendency of the backrest to change the respective intermediate position in the course of movement is very weak, preferably not present.
- the drive power for rotating the seat back can be dimensioned so weakly that the driven movement sequence can be manually stopped or even reversed without any problems, so that appropriate. Sensors that would respond in the presence of an obstacle or that do not require other active safety techniques.
- the rotary movement is carried out by an electrical and / or pneumatic drive.
- This drive preferably has no self-locking.
- the drive is preferably dimensioned such that it can be suppressed and / or overwritten by hand.
- the seat has a locking / unlocking mechanism which moves the backrest in the respective Position, preferably the storage or usage position locked.
- the locking / unlocking mechanism has a pneumatic and / or electric drive.
- the locking / unlocking mechanism is particularly preferably also operable by hand. This embodiment of the present invention has the advantage that in the event of a drive failure, its control or its energy supply, the vehicle seat does not have to be left in the storage or use position, or in particular not in a position that represents a safety risk.
- the drive of the backrest and / or the locking / unlocking mechanism preferably has a preferably electronic control for actuating the drives. Such a control opens up a multitude of additional benefits.
- the control is preferably designed in such a way that undesired, possibly locked positions of the backrest can be avoided.
- An example of an undesirable locked position is a backrest that is not fully lowered and is aimed at the driver's head, which would pose a safety hazard to the driver in the event of an impact.
- the locking / unlocking mechanism is designed to be self-resetting in the event of a drive or control failure, so that the backrest can be automatically locked again in the event of a failure of the respective drive.
- the drive and the locking mechanism are preferably of modular construction, which results in favorable assembly and production processes.
