Patent number: 10967976Abstract: The invention relates to a vehicle seat (1) comprising a seat surface (2) and at last one backrest element (3, 13) which are pivotable about an axis (6) relative to the seat surface (2). The at least one backrest element (3, 13) is movable from a sitting position, in which the backrest element (3, 13) is positioned substantially at an angle (a) relative to the seat surface (2), into a reclined position, in which the seat surface (2) and the at least one backrest element (3, 13) form a substantially planar surface, and back again. The vehicle seat (1) has at least one pneumatic cushion (10; 10.1, 10.2) and a pneumatic unit (9), which is configured in such a way that the pneumatic unit substantially completely inflates the at least one pneumatic cushion (10; 10.1, 10.2) if the at least one backrest element (3, 13) is moved into the reclined position, and the at least one pneumatic cushion (10; 10.1, 10.2) is substantially completely emptied when the backrest element (3, 13) is moved into the sitting position.Type: GrantFiled: December 8, 2016Date of Patent: April 6, 2021Assignee: LANTAL TEXTILES AGInventors: Manuela Glanzmann-Zaugg, Thomas Hertig, Andreas Guehmann

Patent number: 10300824Abstract: A vehicle seat having a seating surface which has a front edge and a rear edge, and a backrest arranged at the rear edge and situated at an angle to the seating surface. The seating surface is divided into a main part and at least one front part. The main part and the at least one front part can be moved relative to one another by means of an adjusting device to enable a distance between the front edge and the rear edge of the seating surface to be adjusted dynamically. At least two inflatable chambers are arranged between the main part and the at least one front part, which chambers can be inflated and emptied in accordance with the distance of the front edge from the rear edge.Type: GrantFiled: April 28, 2015Date of Patent: May 28, 2019Assignee: LANTAL TEXTILES AGInventors: Roland Von Ballmoos, Andreas Guehmann, Oliver Rohrbach

Patent number: 10232754Abstract: The present application relates to a vehicle seat (1) comprising a seat surface (2) and at least one rest part (3.1, 3.2) at an angle to the seat surface (2). The angle between the seat surface (2) and the at least one rest part (3.1, 3.2) is movable via an adjusting device (6, 13) between a first position, in which the at least one rest part (3.1, 3.2) is substantially at right angles to the seat surface (2), and a second position, in which the seat surface (2) and the at least one rest part (3.1, 3.2) form a substantially flat surface. A second end (10.1, 10.2) of the at least one rest part (3.1, 3.2) comprises at least one pneumatic cushion (4) which is fluidically connected to a pump (7), wherein a control device is configured such that the pneumatic cushion (4) is substantially completely emptied when the at least one rest part (3.1, 3.2) moves from the first position into the second position.Type: GrantFiled: April 28, 2015Date of Patent: March 19, 2019Assignee: Lantal Textiles AGInventors: Roland Von Ballmoos, Andreas Guehmann, Oliver Rohrbach

Publication number: 20170151895Abstract: The present invention relates to a vehicle seat (1) having a seating surface (2), which has a front edge (16; 16.1, 16.2) and a rear edge (17), and a backrest (3) arranged at the rear edge (17) and situated at an angle to the seating surface (2). The seating surface (2) is divided into a main part (4) and at least one front part (5; 5.1, 5.2). The main part (4) and the at least one front part (5; 5.1, 5.2) can be moved relative to one another by means of an adjusting device to enable a distance between the front edge (16; 16.1, 16.2) and the rear edge (17) of the seating surface (2) to be adjusted dynamically. At least two inflatable chambers (6, 7; 6.1, 6.2, 7.1, 7.2) are arranged between the main part (4) and the at least one front part (5; 5.1, 5.2), which chambers can be inflated and emptied in accordance with the distance (D; D1, D2) of the front edge (16; 16.1, 16.2) from the rear edge (17).Type: ApplicationFiled: April 28, 2015Publication date: June 1, 2017Applicant: Lantal Textiles AGInventors: Roland VON BALLMOOS, Andreas GUEHMANN, Oliver ROHRBACH
