РЕГУЛИРУЮЩЕЕ УСТРОЙСТВО С МЕХАНИЗМОМ ПРИВОДА ШПИНДЕЛЯ

Изобретение относится к регулирующему устройству для изменения положения с возможностью поворота двух деталей автомобиля относительно друг друга. Регулирующее устройство содержит шпиндель, закрепленный на одной детали автомобиля с возможностью поворота вокруг первой поворотной оси, регулирующий привод, имеющий корпус привода и посредством шпиндельной гайки находящийся в зацеплении со шпинделем, и размещенное на другой детали автомобиля крепление, которое устанавливает регулирующий привод на другой детали автомобиля с возможностью поворота вокруг второй поворотной оси. Крепление образовано U-образной пластиковой поддерживающей скобой (3). Поддерживающая скоба имеет две опорные поверхности (33, 34) на своих плечах, которые обеспечивают гладкую опору для установки регулирующего привода (22). Опорные поверхности (33, 34) по своим очертаниям соответствуют участкам цилиндрической поверхности, расположенной концентрически относительно второй оси поворота. По опорным поверхностям (33, 34) скользит корпус привода (23) регулирующего привода (22), так что регулирующий привод (22) удерживается между плечами, но при этом располагается с возможностью поворота. Достигается создание регулирующего устройства, которое может быть выполнено легким по весу и экономичным, но обладающим при этом высокой эксплуатационной прочностью. 14 з.п. ф-лы, 12 ил.

A RECLINER MECHANISM

A recliner mechanism for a vehicle seat includes a support plate (7) mounted on the squab (2) of the seat, and a support plate (11) mounted on the back rest (3) of the seat. There is a pivotal interconnection (10) between the plates to enable the back rest to be reclined. The pivotal interconnection is initially retained by a spring (20), in a retaining part (15) of an elongate slot (14). When the back rest (3) is subjected to a rearward force, such as by a seat occupant in a rear impact situation, the spring is deformed and the pivot shaft moves along the slot (14), enabling the back rest (3) to move rearwardly. An energy absorbing element (17) is provided which deforms, whilst absorbing energy, during this second movement of the back rest.

Rotatable seat belt buckle mounting bracket for a wehicle seat adjuster with a catcher bracket buckle brace

A track assembly for a vehicle includes an upper track (52) slidably mounted in a lower track (50). A seat belt buckle mounting bracket (102) is attached to the upper track (52) and connects a fixed seat belt to the upper track (52). The seat belt buckle mounting bracket includes first (200) and second (202) angularly disposed legs, with the first leg (200) attached to the upper track (52) and the second leg (202) attached to a fixed seal belt buckle. The attachment structure mounts the seat belt buckle mounting bracket (102) in a first, normal operating position in which the second leg (202) of the bracket extends upward from a side wall of the upper track (52). The attachment structure permits the seat belt buckle mounting bracket (102) to rotate from the first position under a force applied through the fixed seal belt to a second position in which the second leg (202) of the bracket (102) is substantially aligned with the longitudinal axis of the upper track (52) to place the first and second legs of the bracket in tension with the applied force. The second position provides a strong geometry position for the seat belt buckle mounting bracket (102). The attachment structure also includes a catcher strap (220) connecting the seat belt buckle mounting bracket (102) and upper track (52) to the rear torsion bar or tube (42) to increase the ultimate load before failure, and to transfer the load in a manner so that the load is shared between the buckle bracket and the rear torsion bar for subsequent transmission to the rear riser (80).

Rotary seat adjustment mechanism

The rotary adjustment mechanism adjusts the seat back of a vehicle seat. The mechanism includes a handle (40) mounted for rotation with respect to the seat. The handle has an internal gear (74), and the internal gear drives a pair of pinion gears (64, 66) positioned within the internal gear. Each gear rotates a flexible shaft (110, 112), and each shaft connects to a leadscrew (120, 122). The leadscrew has a threaded end, which mates with a threaded nu t (124, 126) connected one seat pivot. Shaft rotation rotates the leadscrew, which causes the threaded nut to move axially, which in turn, pivots the respective seat pivot.

The spindle nut wheel for radially supporting a rolling bearing (15), is arranged between a pipe portion (8) and the hollow cylinder. An independent claim is included for motor adjustable seat.

Linearly infinitely variable mechanism

A linearly infinitely variable mechanism comprises first and second portions which are relatively axially positionable to establish the effective length of the mechanism. A rotary element is axially captured on the second portion. The operative connection between the first portion and the second portion is via a threaded connection of the first portion with the rotary element. The axial capture of the rotary element comprises a twist lock which, when locked, forcefully abuts the ends of the rotary element to preclude its rotation and prevent a change in the effective length of the mechanism provided that the first and second portions are constrained against relative rotation. When unlocked, the rotary element can rotate within its axial capture so that axial forces applied to the mechanism are effective to change its length. Recesses are provided between the element and the twist lock and contain yieldably resiliently mounted bearings which promote free rotation of the element when unlocked but which retract into the recesses when locked.

Linear recliner assembly with threaded linear drive rod and rotatably engaged gear stop

A linear recliner assembly in use with a seat having a seat back pivotally engaged relative to a seat bottom. A housing exhibits a communicating interior between a first and second ends. A drive rod is supported in linearly displaceable fashion from the first end and is secured to the seat bottom. The second end pivotally engages the seatback spaced from its pivot point. A rotatable gear located at a fixed lineal position within the housing receives the drive rod in threadably inter-engaged fashion. A trigger mechanism pivotally secured to the housing exhibits a downwardly biased detent communicating through an opening in the housing to seat between succeeding teeth of the gear. A spring supported within the housing contacts the drive rod. Upon release of the detent, a reclining force applied to the seatback results in displacement of the housing against the drive rod to bias the spring. The spring influencing the drive rod in a reverse direction such that, upon release of said detent when the seatback is in the reclined position, the spring influences the seatback to reverse pivot to a returned upright position.

Vehicle seat lock mechanism

An automotive vehicle includes a lock mechanism for locking a seat slide unit on which a vehicle seat is mounted or a seat reclining unit mounted on the vehicle seat. A screw rotatably mounted on an upper rail is in mesh with a nut secured to a lower rail or mounted on a seat back frame. Each of the screw and the nut has a lead angle greater than an angle of friction thereof so that the screw can rotate in response to a load applied to the vehicle seat or a seat back, thus enabling adjustment of the position of the vehicle seat in a direction longitudinally of the vehicle body or that of the angle of inclination of the seat back. If deceleration or acceleration of a value not smaller than a predetermined value is applied to the vehicle seat, the screw is urgently locked to thereby maintain the current position of the vehicle seat or the current angle of inclination of the seat back.

The invention concerns a vehicle seat with integral seat belt (5). The frame of the back comprises a lateral beam (7) which is highly resistant to flexure and carries the upper anchoring point P of the seat belt and a lower cross piece (8) fixed to the base of the beam and sufficiently strong to prevent the transverse inclination of this beam and a strut (10) at its ends mounted in a pivoting manner respectively about a transverse axis B associated with the front of the base (1) and about a transverse axis C which is part of the beam (7) and disposed at a distance from the transverse axis A of pivoting of the back (4) which is less than 1/6 of the distance separating this axis A from the upper anchoring point P of the seat belt, means acting on the strut to adjust the position of the axis C about the axis A. <IMAGE>
