摘要:
A belt tightening device (100/100') for use with a safety device such as a seat belt buckle: a flexible member (12), such as an anchoring length of seat belt webbing, operatively connected to the safety device (34); a housing (102) including a first opening (110) through which the flexible member loosely extends; first and second relatively movable clamping members (160, 162) for causing a portion of the flexible member extending from the housing to be drawn into the housing thereby shortening the remaining length of the flexible member causing a safety belt operatively attached to or part of the flexible member to become more tightly disposed about a user thereof.
摘要:
A seat belt retractor (20) characterized by low mass and low operating noise, resistant to dust, moisture, and corrosion comprising: an integrally formed, quadrilaterally shaped main body portion (24). In the preferred embodiment of the invention the frame is injection molded using 50% or greater long glass fiber plastic or die cast or injection molded metal. A spring housing wall and wall of a mechanism cover are also integrally formed in the sides of the retractor. Positioned within the spring housing wall is a spring coil guide, as well as an integrally formed anchor, which is used to hold the outer end of a rewind spring. The mechanism side of the frame further includes an integrally formed post or pin to pivotally support a locking pawl.

An airbag module (10) employing a deflagration venting system (40) for adaptively changing the level of venting provided during airbag inflation is disclosed. The adaptively controlled airbag system (10) includes an airbag (12) in fluid communication with an airbag inflator (18). A manifold (16) is provided for directing the output of the airbag inflator (18) into the airbag (12), and a reaction canister (22) houses the airbag (12), the airbag inflator (18), and the manifold (16). A deflagration device (40) is provided for selectively venting the airbag module (10). The deflagration device (40) may be activated for creating at least one variable shaped vent (50, 52) for regulating output from the airbag inflator (18) and adaptively changing the deployment force of the airbag (12).

An apparatus (10) for a vehicle includes a child seat (54) for holding a child. A support device (16, 44) supports the child seat (54) on a seat (12) of the vehicle for movement relative to the seat (12) during a collision in which at least one condition exceeds a predetermined threshold. An energy absorbing device (60) absorbs kinetic energy of the child and the child seat (54) during such relative movement. The support device may include support bars (16) that permit sliding movement of the child seat (54) relative to the support bars (16) and the vehicle seat (12). Several types of energy absorbing devices may be used, including compressible bellows (60), cuttable strips of sacrificial material (108), crushable pieces of sacrificial material (154), deformable projections (188), a payout device (250) with webbing (296), compressible shock absorber assemblies (340), and slidable frictionally engaging portions (392 and 396).

An improved safety apparatus (10) is used in association with a belt (16) which restrains movement of an occupant of a vehicle. The belt (16) is taken up by and paid out from a retractor assembly (22). Upon the occurrence of vehicle deceleration greater than a predetermined deceleration, a solenoid assembly (132) operates a clamp assembly (28) to grip the belt (16) and prevent paying out of the belt. In one embodiment of the invention, the retractor assembly (22) includes a sensor assembly (54) which operates a retainer assembly (56) to prevent withdrawal of the belt from the retractor assembly when the deceleration of the vehicle is in excess of a predetermined deceleration. The sensor assembly (54) is mounted on a movable carriage (32) in the retractor assembly (22). Although the clamp assembly (28) and the retractor assembly (22) may be used in many different locations in a vehicle, they are advantageously located on the back (24) of a vehicle seat (12).

A multiple function control stalk for a vehicle having a pivotable headlight dimmer switch therein is disclosed. The control stalk can house a plurality of electrical switches for controlling various devices within the vehicle, such as windshield wiper and washer controls and vehicle speed or cruise controls. The control stalk is pivotally connected to a turn signal lever of the vehicle such that it can be pivoted toward the driver in a plane of movement which is generally perpendicular to the plane defined by the plane of movement of the turn signal lever itself. A two position electrical switch is provided within the control stalk. The switch includes a plunger which is engaged by pivoting movement of the control stalk relative to the turn signal arm to move from a first position to a second position, and vice versa. The switch can be utilized to control the operating condition of the headlights, namely, low beam or high beam, or other controlled device in the vehicle.

A vehicle seat belt retractor (10) has a spool (20) on which seat belt webbing (26) is wound. An externally-toothed ratchet wheel (50) is rotatable with the spool (20) in a belt withdrawal direction (22). A first pawl (70) is supported on a housing (12) for pivotal movement about a first axis (72) into engagement with the ratchet wheel (50) to block rotation of the ratchet wheel (50) in the belt withdrawal direction (22). An inertia member (62) supported on the housing (12) is movable in response to vehicle deceleration greater than a predetermined deceleration to pivot the first pawl (70) into engagement with the ratchet wheel (50) and thereby block rotation of the ratchet wheel (50) and the spool (20) in the belt withdrawal direction (22). A second pawl (90) is supported on the housing (12) for pivotal movement relative to the ratchet wheel (50) about a second axis (92) spaced from the first axis (72). The first pawl (70) has a portion for supporting the second pawl (90) and for effecting movement of the second pawl (90) about the second axis (92), upon movement of the first pawl (70) about the first axis (72), into a ready position. The second pawl (90), when in the ready position, is engageable with the ratchet wheel (50) to block rotation of the ratchet wheel (50) and thus of the spool (20) in the belt withdrawal direction (22).
摘要:
An improved apparatus for interconnecting safety belts includes a buckle member which receives a tongue member to interconnect the safety belts. An indicator and ejector assembly has a visually readable indicia which changes from red to green as the tongue and buckle members are interconnected. As the tongue and buckle members are disconnected, the indicia changes from green back to red. The indicia is disposed on an indicator member which transmits force to eject the tongue member at least partially from the buckle member as the tongue and buckle members are disconnected.
