Abstract: An auxiliary drive device for a wheelchair has at least one freely pivotable electrically driven drive wheel and a coupling mechanism for coupling the auxiliary drive device to the wheelchair. The coupling mechanism includes a movable locking element which is movably supported in the coupling mechanism. The movable locking element can be in a locking position in which it causes locking in a positive-locking manner so that the auxiliary drive device is coupled to the wheelchair and, by operation of a handle, the locking element can be moved in a release position in which uncoupling of the auxiliary drive device from the wheelchair is possible.

Abstract: A vehicle seat includes a backrest and a seat part, at least one of which has a structural element with a cavity. At least one part of the cavity receives an insert in the region of a filling. The insert is connected to the structural element in a positively locking fashion at least with regard to one type of movement. The insert is bonded to the filling.

Abstract: A vehicle seat includes a seat part and a partitioned back rest. The back rest has a first segment and a second segment. The segments are each equipped with an inclination adjuster. The adjusters include means for limiting the inclination of one segment relative to the other.

Abstract: A vehicle seat includes a seat part and a backrest which is provided at the seat part so as to be rotatable, wherein the seat part and the backrest can be transferred into an easy entry position.

Abstract: A drive assistance device for a wheelchair includes a drive motor, a running wheel and a sensor device which is adapted to determine a driving force manually induced into the running wheel; and a control unit which is adapted to control the drive motor for driving the running wheel depending on the driving force manually induced by the user into the running wheel. The control unit of the drive assistance device includes a user force analysis operational mode which is adapted to determine data concerning physical efficiency and capacity of the user. These include a maximum force of the user as well as the maximum speed which can be reached with purely manual drive.

Abstract: A vehicle seat includes a backrest and a seat part, at least one of which has a structural element forming a cavity. A filling is disposed in the cavity and configured to influence the stability and/or the deformation behavior of the backrest and/or the seat part. The filling comprises a foam support and a foam material that at least partially surrounds the foam support.

Abstract: The invention relates to an adjusting device, in particular for the seat of a motor vehicle, comprising at least one first rail (lower rail (1)) and one second rail (upper rail 2)) which is embodied in a displaceable manner in relation to the first rail, in addition to a spindle (4) which is connected to the first rail and a drive housing (14) which can be penetrated by the spindle and which is arranged on the second rail, said drive housing being provided in order to receive at least one gear element which co-operates with the spindle. According to the invention, the drive housing is secured in a directly positive manner to the associated rail but also in a manner whereby the height can be adjusted.

Abstract: A vehicle seat includes a backrest and a seat part, at least one of which has a structural element with a cavity. The cavity is formed by a base plate and at least two profiles secured to the base plate. A corner region of the two profiles has provided in it a filling configured to influence the stability and/or the deformation behavior of the backrest and/or the seat part. The filling has a foam support and a foam material at least partially surrounding the foam support.

Abstract: An adjusting device for a vehicle seat includes a brake housing that is centered about an actuating rotational axis. The brake housing is formed in a radial direction of the actuating rotational axis and includes a housing element that is generally circular and has a outer side wall, and upper wall and an inner side wall.

Abstract: A vehicle seat includes a seat part having a seat substructure. The seat part is displaceable along a transverse axis with respect to the seat substructure and the seat part is at least partially swivelably about the transverse axis. The seat includes a displacement element having a displacement length, a fixed lower part and an upper part. A first longitudinal movement of the seat part and a first transverse movement of the seat part occurs along a first section of the adjustment length. A second longitudinal movement of the seat part and a second transverse movement of the seat part occurs along a second section of the adjustment length. The ratio of the first longitudinal movement to the first transverse movement differs from the ratio of the second longitudinal movement to the second transverse movement.
