Abstract:
A traction cable actuator has a sun gear (62, 162) with a lever (64, 164), planetary gears (40, 140) engaged with the sun gear (62, 162), and a housing (10, 110). The housing (10, 110) includes a toothed race (16, 116) and a lock spring seat (20, 120). A drive shaft (70, 170) has at least one release tab (80, 180) and engages with the sun gear (62, 162) to turn it. A pulley (30, 130) is disposed within the housing (10, 110) and has planetary gear axles (32, 132) disposed to receive driving force from the planetary gears (40, 140). A lock spring (50, 150) disposed to engage said lock spring seat (20, 120) in the housing (10, 110) engages the lever (64, 164) on the sun gear (62, 162) when the sun gear (62, 162) is turned. The lock spring (50, 150) holds said pulley (30, 130) in a position selected by turning the drive shaft (70, 170). A bearing (202) and groove (204) stop assembly may be included.
Abstract:
L'invention concerne un dispositif de transmission d'un mouvement de rotation (1) et un système de réglage de siège de véhicule automobile comprenant un tel dispositif. Le dispositif de transmission comprend un arbre flexible (2) et une gaine (3) à l'intérieur de laquelle l'arbre (2) est logé, la gaine (3) comprenant une âme (4) formée d'un cylindre creux dont le diamètre intérieur est agencé pour permettre la rotation dudit arbre (2) à l'intérieur de ladite âme (4). L'âme (4) du dispositif comprend au moins une zone formant palier (6) qui est obtenue par déformation plastique, la zone (6) comprenant au moins trois parties, deux parties extérieures (7, 8) et une partie centrale (9). Ces parties (7-9) présentent des axes sensiblement parallèles à celui de l'âme (4) et sont de diamètre sensiblement égal à celui de l'âme (4), les parties extérieures (7, 8) étant sensiblement coaxiales et d'axe décalé par rapport aux axes de la partie centrale (9) et de l'âme (4).
Abstract:
Continuous seat adjustment apparatus is used in conjunction with a seating device including a track assembly having an inner track and an outer track (16) longitudinally movable on the inner track (15). The apparatus includes a pair of movable jaws (35,36) mounted on the outer track for pivotal movement between first and second orientations. Each of the jaws defines an opening (37,38) with the inner track longitudinally extending therethrough. The jaws frictionally engage the inner track in the first orientation to substantially prevent longitudinal movement along the inner track and the jaws release the inner track in the second orientation to allow continuous longitudinal movement along the inner track. A spring device (40) is affixed to the pair of opposed jaws to provide a bias on the jaws tending to move the jaws into the first orientation and an adjustment member (22) is provided for moving the jaws against the spring bias from the first orientation to the second orientation.
Abstract:
The present invention involves a friction lock device (10, 110, 710, 810) which utilizes one or more friction springs (80, 120, 180) coaxially disposed about a translating rod (30, 130, 730, 830) within an elongated housing (51, 151). Bias bushings (70, 160, 170) are provided for slidably supporting the rod adjacent one end of each spring. Each bushing defines a sloped shoulder (76, 166, 176) against which the friction spring bears, with the angle (78, 168, 178) of the shoulder calibrated such that the spring is canted to provide a holding force up to a predetermined axial force on the rod, and to permit the rod to slip relative to the spring at greater axial forces without disturbing the integrity of the spring or its coils (83). The device includes a release or actuation mechanism (90, 190) to partially unwind the springs, thereby reducing the gripping force of the springs and freeing the rod to slide through the springs.
Abstract:
The mechanical lock (10) includes a rod (30) having one end extending into a housing (14) and another end extending out of the housing. The rod translate through bores through bushings (40) within the housing. Coil springs (60, 61) in the housing and surround the rod. When the springs are in their normal orientation, they grip the rod tightly and prevent the rod from translating. The rod and bushings have complementary structure for preventing the rod from rotating within the bushings and housing. In the exemplary embodiment, the structure are flat surfaces (31) along the rod and the bushing that mate with each other.
Abstract:
The invention relates to a spindle or worm drive for adjusting devices, especially seat adjustment devices, window lifters and sliding roofs, in motor vehicles. The inventive drive consists of a fixed spindle or relatively fixed toothed rack which is secured to the first of two parts that can be adjusted in relation to each other and to a gear which is secured to the second of said two parts. The gear elements (91; 92; 92') are mounted in a housing (7) which consists of at least two plates (71a; 71b; 72a; 72b) that can be secured to each other by means of plug-type connectors. Said connectors are also configured as supporting joints that absorb the forces of the gear.
