Abstract:
An apparatus (40) for pretensioning seat belt webbing (16) which is extensible about an occupant of a vehicle seat (14) has at least two different output levels. Sensors (110, 120, 130) sense at least one characteristic of the occupant of the vehicle seat (14). A controller (100) is operatively connected to the sensors (110, 120, 130) for controlling the output level of the pretensioning apparatus (40) based on the characteristics of the occupant sensed by the sensors. The at least two output levels of the pretensioning apparatus (40) correspond to respective levels of force applied to the seat belt webbing (16) which in turn correspond to respective levels of force imposed on the vehicle occupant by the seat belt webbing.
Abstract:
In a seat belt system (10), a plurality of sensors (76, 80, 84) sense characteristics of a vehicle occupant and of a vehicle collision. The vehicle occupant sensors (80, 84) cooperate with a controller (90) to control a motor (60) which sets the position of a movable D-ring stop (70). The position of the stop (70) determines the position to which a movable D-ring (28) is repositioned in the event of a vehicle collision. The system (10) also includes a retractor (30) supported for movement on the vehicle. A crushable energy absorbing material, preferably a honeycomb (230), is disposed in the path of movement of a crush plate (160) movable with the retractor (30). The crushable material (230) controls movement of the crush plate (160) and thus of the retractor (30). Together with the repositioning of the D-ring (28), this reduces the abruptness of the load on the vehicle occupant during a vehicle collision.
Abstract:
This disclosure deals with a window regulator assembly as a unit such as for vehicles and specifically vehicle doors, which doors have rigid frames so that the assembly may be installed in any type or shape of door, and the three parts of this assembly that are attached to any adjacent panel in the door after the door or wall in which it is to be installed has already been assembled. This assembly comprises a flexible plastic tape which may be twisted and bent in any direction, the opposite ends of which tape are wrapped around reversible motor or manually-driven drums so that as one end is wrapped, the other is unwrapped, and vice versa. These drums comprise the driving part of this assembly that is attached to a door. The tape also has a substantially straight vertical reach intermediate its ends, the length of which reach may be fixed by the length of a flexible plastic strip along this reach of the tape. This vertical reach of tape or strip has guides at its ends that comprise the two other parts of this assembly, which guides preferably surround the tape to insure the assembly as a unit. These two guide parts are attached to the door and are for changing the direction of the tape to extend toward the drums. A crimping and clamping device is attached to the straight vertical reach of the tape and to a carrier for the window that is to be opened and closed or regulated by the reciprocation of this vertical reach of tape. The tension in the tape is maintained by resiliently supported rollers in contact with the tape away from this substantially straight reach, which rollers may be mounted on the driving part or on a fourth part of this unitary assembly that also is separately attached to a door.
Abstract:
A modular sliding roof panel assembly for a vehicle having an opening in the roof. The sliding roof panel assembly includes a movable roof panel having front and rear guide shoes engaging guide tracks mounted to an integrally formed plastic housing affixed to the interior side of the vehicle roof. Guide blocks secured to the longitudinal edges of the movable roof panel have cam tracks formed therein which are engaged by a cam follower mounted on the rear guide shoes to lower the rear edge of the movable roof panel below the stationary roof of the vehicle as the roof panel slides to the open position and to raise the rear edge of the roof panel above the stationary roof structure when the movable roof panel is pivoted about the front end. A water trough extending transversely across the rear edge of the housing is connected to the front guide shoes for sliding movement therewith. A detector for detecting the position of the movable roof panel is connected to a drive unit and actuator switches for controlling the movement of the movable roof panel between sliding and flip-up modes of operation.
Abstract:
An occupant protection apparatus comprises an inflatable airbag with a panel, the panel including a first vent opening that permits inflation fluid to escape out of the airbag; and a valve sheet including a second vent opening movable relative to the first vent opening, the valve sheet having opposite ends that are each fixed to a surface of the airbag. One end of the valve sheet moves with the panel during inflation of the airbag to move the second vent opening relative to the first vent opening. The apparatus also includes a valve guide or envelope to guide movement of the valve sheet relative to the panel, the valve sheet is capable of sliding between the valve guide and the panel. Both ends of the valve sheet remain fixed to the panel during and after inflation of the airbag. The valve sheet includes a tear tab to temporarily retain the valve sheet to the panel.
Abstract:
An airbag assembly includes an airbag and a system provided in contact with at least a portion of the airbag that includes a first member and a second member. The second member at least partially overlaps the first member and is held in contact during initial deployment of the airbag with the first member by a frictional force between the first member and the second member. The system is configured to cause the airbag to inflate laterally with respect to a vehicle occupant until the frictional force is overcome by inflation of the airbag.
Abstract:
A seat belt buckle (12) has a light-transmitting portion (26) which is visible to a vehicle occupant. The buckle (12) includes a housing (60) containing a latch mechanism (20) which releasably locks a seat belt tongue (16) in the housing (60). The housing (60) further contains a light source (70) and optical fibers (72) for conducting light from the source (70) to the light-transmitting portion (26) of the buckle (12).
Abstract:
An apparatus (20) controls the position of an occupant (32) in a vehicle passenger compartment by sensing physical characteristics of the occupant such as weight, height, girth, and leg length. A controller (36) controls seat motors (92, 94, 96) to move the occupant (32) to a position based on the sensed physical characteristics of the occupant. The occupant (32) can override the system using override controls (98). The controller (36) also adjusts the performance of an occupant restraint (22) in response to a selected occupant position.
Abstract:
The disclosure concerns a regulator for moving a window in a vehicle door ccessively substantially vertically and horizontally and vice versa. In other words, once the window is closed vertically the lower edge may be moved outwardly horizontally to become more flush with the outside surface of the door of the vehicle. The regulator comprises a closed loop of cable wrapped about a reversible driving drum and having a vertical reach which is attached to a pulley connected to the carrier for the window. This pulley is provided with a pair of diametrically opposite cam follower pins or rollers that are guided in a vertical slot parallel to the vertical reach of cable, which slot has a bifurcated or Y-shaped pair of slots at its upper end for rotating the pulley up to about 180.degree. when the pulley reaches the "Y" and the cable means continues to pull. The pulley also has a helical groove axial and integral therewith for positively screwing the carrier attached to the lower edge of the window outwardly horizontally. This carrier has a socket with a radial pin therein fitting into said helical groove so that oscillation of said pulley produces the horizontal reciprocating motion of the carrier and lower edge of the window. When the cable then pulls in the other direction on the pulley, it positively screws the window carrier inwardly horizontally before lowering the window carrier to open the window.
Abstract:
An airbag module includes a housing having at least one aperture for releasing gas from an interior of the housing during inflation of an airbag. The airbag module also includes a member configured for movement between a first position in which the member impedes the flow of gas through the at least one aperture and a second position in which the member does not impede the flow of gas through the at least one aperture. A pyrotechnic device is attached to the member for directing a burst of gas toward a fixed surface to cause the member and the pyrotechnic device to move between the first position and the second position.
