Patent number: 5269588Abstract: A vehicle seat, especially a motor vehicle seat, includes an adjustable device which permits adjustment of the seat part, relative to the freely pivotable backrest. The cushion support of the seat part, at least in one position of the cushion support above its lowermost position, can be moved before or at the beginning of a free pivoting motion of the part of the backrest forwards and/or downwards at least in the region of its rear section, and can be moved back into its starting position after or while the backrest pivots back into its starting position.Type: GrantFiled: February 6, 1991Date of Patent: December 14, 1993Assignee: Keiper Recaro GmbH & Co.Inventors: Holger Kunz, Hans W. Voss, Heinz P. Cremer

Patent number: 5143421Abstract: A vehicle seat which is adjustable both with regard to its height and angle of inclination has front and rear height mechanisms which can be operated independently of one another. Each of the height adjustment mechanisms has at least one lever, which levers are pivotable about an axis running in the lateral direction of the seat. The upholstery support of the seat is supported on support points of these levers, which lie at a distance from their pivot axes. The front and rear height adjustment mechanisms are connected with a coupling drive, which, when the front height adjustment mechanism is activated limits the height adjustment of this front height adjustment mechanism, and when the rear height adjustment mechanism is activated, the height adjustment of the support point thereof is transferred to the support point of the front height adjustment mechanism.Type: GrantFiled: October 31, 1990Date of Patent: September 1, 1992Assignee: Keiper Recaro GmbH & Co.Inventors: Hans W. Voss, Heinz P. Cremer, Harald Cwiertnia, Peter-Ulrich Putsch

Patent number: 4685739Abstract: An upholstery support for the back rest of a vehicle seat, particularly a motor vehicle seat, has two reinforced half-shells connected with each other along a portion of their edges. The half-shells form hollow box-like arms which distance themselves from each other from a hollow box-like joining area toward their free ends. The free ends of both arms form the lower end of the upholstery support, which has a V-like shape that is open toward the lower end.Type: GrantFiled: June 11, 1986Date of Patent: August 11, 1987Assignee: Keiper Recaro GmbH & Co.Inventors: Elmar Deegener, Hans W. Voss, Gunter Franzmann

Patent number: 4685727Abstract: A vehicle seat has a back rest and support surface for supporting the vehicle user, in which at least one portion of the support surface facing the seat user forms at least the outside of a wall, the inner side of which wall borders at least one channel through which air flows. The wall is at least substantially impermeable to air at the pressure prevailing in the channel and comprises a material which, when there is a drop in the water vapor partial pressure from the outside to the air flowing through the channel, transfers water vapor in the direction of this partial pressure drop.Type: GrantFiled: March 26, 1986Date of Patent: August 11, 1987Assignee: Keiper Recaro GmbH & Co.Inventors: Heinz P. Cremer, Werner Wittig, Hans W. Voss

Patent number: 4648654Abstract: The present invention refers to an adjustable seat, particularly for use in buses and trucks. There is described an adjustable seat having a seat portion and a back portion, which permits the correct simultaneous positioning of the back, arms, and legs of a driver irrespective of his stature. The seat includes an adjustable seat portion which may be moved longitudinally towards or away from the seat back portion, such longitudinal movement being accompanied by a simultaneous rotation of the seat portion about a first transverse axis, the angle between the seat portion and the back portion increasing or decreasing as a result of longitudinal motion of the seat portion. There is also described a second mechanism which allows a limited angular rotation of the seat portion about a second transverse axis.Type: GrantFiled: February 21, 1984Date of Patent: March 10, 1987Inventor: Hans W. Voss

Patent number: 4186904Abstract: An adjustable seat of a motor vehicle has a mounting arrangement at each of its lateral regions. The respective mounting arrangement includes an elongated carrier, a support rail which is connected to the seat proper and is displaceable longitudinally of the carrier, and a pivot which mounts the carrier, which extends in the front-to-rear direction, for tilting along a vertical plane. A drive and a driving section of a transmission are mounted on the carrier, the driving section including two pinions which are simultaneously driven by the drive and one of which meshes with a driven rack rigidly connected to the support rail, while the other pinion meshes with another driven rack which is provided at one side of an elongated slot in a support element for the seat proper and is curved having its center of curvature on the axis of the above-mentioned pivot.Type: GrantFiled: September 14, 1977Date of Patent: February 5, 1980Assignee: Keiper Automobiltechnik GmbH & Co. KGInventors: Adolf Reinmoller, Hans W. Voss, Bernd Kluting

Patent number: 4141583Abstract: A motor-vehicle seat displaceable relative to a fixed support in a motor vehicle between a pair of end positions is powered by a motor whose output shaft may be rotatable in only a single predetermined rotational sense. Mechanism is provided having an input rotatable in one direction for displacing the seat on the support of the motor-vehicle from one end position into the other end position and rotatable in the other opposite direction for displacing the seat on the support from the other end position into the one end position. A motion-converting transmission is connected between the output shaft of the motor and the input of the displacement mechanism for automatically driving this input alternately in the one direction and in the other direction on continuous rotation of the motor output shaft in only the one sense.Type: GrantFiled: November 25, 1977Date of Patent: February 27, 1979Assignee: Keiper Automobiltechnik GmbH & Co. KG.Inventors: Bernd Kluting, Hans W. Voss

Patent number: 4128225Abstract: An adjustable automobile seat includes a base member, a carrier member for supporting a load, and support legs intermediate the base and carrier members. An actuating handle vertically moves the carrier member relative to the base member to thereby adjust the position of the seat. Eccentric gears are provided intermediate the base and carrier members for maintaining the torque which is necessary for turning the handle substantially constant during the movement of the carrier member.Type: GrantFiled: May 31, 1977Date of Patent: December 5, 1978Assignee: Firma Fritz Keiper KGInventors: Bernd Kluting, Hans W. Voss
