Patent number: 11845369Abstract: An upholstery unit (28) for a seat of a motor vehicle has bar-form upholstery elements (30) that can be displaced relative to one another and provide a person with cushioned support. A flexible connecting layer (32) connects the upholstery elements (30) to one another and can be folded into an interspace (34) between adjacent upholstery elements (30). The upholstery element (30) has at least one pocket (36), and at least one pressure-point actuator (38) is inserted in the pocket (36) of the upholstery element (30) to apply a massage pressure to the person through a material of the upholstery element (30). The pressure-point actuators (38) in the accommodating pockets (36) of the upholstery elements (30) can be displaced relative to one another. Thus, a massage function of the upholstery unit (28) is adapted optimally to people of different heights, and provides comfortable seating in a motor vehicle.Type: GrantFiled: June 30, 2022Date of Patent: December 19, 2023Assignee: Dr. Ing. h. c.

Patent number: 9975456Abstract: A vehicle seat with a seat part, a backrest and a fitting which pivotally connects the backrest with the seat part. The fitting includes a backrest-side fitting part coupled with the backrest via a locking mechanism, and a rotary fitting mechanism. A driving device is arranged on the backrest for driving the rotary fitting mechanism. In a locking position, the locking mechanism firmly couples the backrest-side fitting part with the backrest, and in a free-pivoting position decouples the backrest-side fitting part from the backrest, so that the backrest is pivotable into a folded position in a swivel direction about the swivel axis. The driving device is formed to actuate the rotary fitting mechanism for pivoting the backrest-side fitting part by a predetermined angle against the swivel direction, when the locking mechanism is actuated for pivoting the backrest into the folded position.Type: GrantFiled: May 15, 2012Date of Patent: May 22, 2018Assignee: Brose Fahrzeugteile GMBH & Co.
