Patent number: 10493873Abstract: A hardware system, for a vehicle seat, includes a fitting (10) having a first fitting part (11) and a second fitting part (12), which can be locked to one another and can rotate in relation to one another about an axis (A), a transmission rod (7) and a hand lever (5), the actuation of which rotates the transmission rod (7). The fitting is unlocked via a rotation of the transmission rod against a total characteristic torque (Moverall), produced from a sum of a first characteristic torque (M35), generated by a spring assembly (35), and a second characteristic torque (M61), generated by spiral springs (61). A first component (63) is rotationally fixed to the transmission rod and a second component (64) moves relative thereto during unlocking. The spiral springs (61) act between the first component (63) and the second component (64). A vehicle seat is provided having the hardware system.Type: GrantFiled: March 7, 2016Date of Patent: December 3, 2019Assignee: Adient Luxembourg Holding S.à.r.l.Inventors: Rolf Schueler, Bernd Bossmanns

Patent number: 9469221Abstract: A fitting system for a vehicle seat having a fitting (10), which has a first fitting part (11) and a second fitting part (12), which fitting parts can be locked to one another and can be rotated relative to one another about an axis (A). A transmission rod (7) rotates during an unlocking process to unlock the fitting (10) against the torque and follows a characteristic curve (M35) generated by a spring arrangement (35). A hand lever (5) initiates the unlocking process, the actuation of which rotates the transmission rod (7). A shaped spring (61) is active between a first component (63) and a second component (64) which rotate, relative to one another during the unlocking process. The torque generated by the shaped spring follows a non-linear characteristic curve (M61) which, together with the approximately linear characteristic curve (M35) of the spring arrangement (35), produces an overall characteristic curve (Moverall).Type: GrantFiled: June 15, 2012Date of Patent: October 18, 2016Assignee: KEIPER GMBH & CO.
