Abstract:
The invention relates to an actuating device (10) for a vehicle seat adjustment system, especially a motor vehicle seat. Said device comprises a pivotable hand lever (12) which is used for manual actuation, is eccentrically positioned and interacts with the adjustment system. The inventive device is provided with an acceleration-sensitive means which is used to fix and/or lock the hand lever (12) in the event of a collision.
Abstract:
The invention relates to a detent fitting that is provided with a solid fitting component (10) appurtenant to the seat component and a fitting component (12) appurtenant to the backrest. The fitting component (12) is pivotably mounted in relation to said first component (10). At least one lock (17) is provided on a fitting component and said lock, together with the remaining fitting component, can be brought into or removed from a locking position in the radial direction. The lock, together with transmission members, forms a backrest adjustment device (17, 20, 21) which engages with an operating lever (27). The aim of the invention is to pivot the backrest towards the front and to bring back said backrest into the position of inclination that has been adjusted before. A memory device (30, 31, 34, 37; 34, 65, 66) and a self-pivoting device (43, 47; 64, 70, 71) that can be released by a separate operating element (45) are assigned to the backrest adjustment device (17, 20, 21).
Abstract:
A seat for vehicle (10) having switching mechanisms for switching a seat condition and capable of surely operating the switching mechanisms, comprising an input side switching mechanism (50) to which an operating force is input, an output side switching mechanism (70) operated in synchronous with the input side switching mechanism (50), and a control cable connected to the input side switching mechanism (50) and output side switching mechanism (70) and transmitting the operating force input into the input side switching mechanism (50) to the output side switching mechanism (70), the control cable comprising a strand type outer casing and an inner cable inserted movably into the outer casing, wherein, because a strand type of outer casing is used for the outer casing of the control cable, the outer casing is prevented from being contracted and a stroke loss is suppressed, and thus the operating force input into the input side switching mechanism (50) is transmitted, with less loss, to the output side switching mechanism (70) so as to surely operate the output side switching mechanism (70).
Abstract:
A vehicle seat assembly includes a seat bottom and a seat back supported for pivotal movement relative to the seat bottom such that seat back position can be adjusted to a variety of reclined positions with respect to the seat bottom. The seat includes a manual or electrical actuator which provides input to a control assembly that pivots the seat back with respect to the seat bottom. The control assembly includes an epicycloide gear mechanism with a first gear supported on the first seat member and a second gear supported on the second seat member. The second gear has a plurality of gear teeth that selectively mesh with a plurality of gear teeth on the first gear. The first gear teeth have a non-epicycloide tooth profile and the second gear teeth have an epicycloide tooth profile. An input member defines an axis of rotation and provides rotational input to the second gear. The input member is an eccentric input shaft having a geometric center that is spaced apart from the axis of rotation. This eccentricity causes the second gear teeth to move into engagement with the first gear teeth. When the input shaft is rotated in a first direction, the second gear is caused to rotate in a second direction, opposite from the first direction, resulting in the seat back pivoting with respect to the seat bottom.
Abstract:
A rack (20) mounted within the housing (12) of a mechanical lock translates. The rack, which has a rectangular cross section, has teeth (22). A toothed pawl (120) pivots within the housing between a locked and unlocked position. The teeth on the pawl engage the rack teeth when the pawl is locked. The pawl has a window (62) that receives a cam (80). The cam has a first surface that engages a surface of the window when the cam is in the locked position. In that position, the cam prevents movement of the pawl teeth away from the teeth on the rack. A second surface of the cam pushes against a different surface of the window when the cam is in the unlocked position. In that position, the cam disengages the pawl teeth from the rack teeth. The window has a chamfered surface to move the pawl to its locked position.
