Abstract:
A belt tightener (10) for a vehicle safety belt system is connected to a seat belt buckle (16). A piston (34) located in a cylinder (32) of a driving mechanism (18) is connected to the buckle (16) by a cable (22). A gas generator (38) produces gas in response to a vehicle collision to move the piston (34) and the buckle (16) in a first direction (20) along a longitudinal axis (42) of the cylinder (32). The cylinder (32) is fixedly mounted on a support member (70) with the longitudinal axis (42) of the cylinder (32) extending along the first direction (20). The support member (70) includes a mounting portion (72) connectable to a vehicle (12). A cover (100) defines a chamber (102) in which the support member (70) and the driving mechanism (18) are located. A flexible boot (130) into which the cable (22) extends is connected to the cover (100) and extends between the buckle (16) and the cover (100).
Abstract:
An apparatus (10) for tensioning safety belt webbing (16) during sudden vehicle deceleration includes a buckle (22), a telescoping frame (26) and an actuator drive (28). The telescoping frame (26) includes first and second frame segments (40) and (42). The buckle (22) is attached to the first frame segment (40). The second frame segment (42) is anchored to the vehicle. The frame segments (40, 42) have a common axis (20) and are slidable relative to each other along the axis (20) to reduce the overall length of the telescoping frame (26). The actuator drive (28) is axially aligned with the telescoping frame (26) and includes a cylinder (138) and a piston (140). The cylinder (138) and piston (140) are movable relative to each other to lengthen the actuator drive (28). The actuator drive (28) is interconnected with the telescoping frame (26) such that lengthening of the actuator drive (28) causes shortening of the telescoping frame (26) to move the buckle 22 and tension the safety belt webbing 16.
Abstract:
A control switch assembly for cruise controls and the like includes multiple mounting adapters which facilitate mounting to a variety of vehicles. The switch assembly housing is a rectangular parallelepiped which defines a mounting structure. The mounting structure receives one of a plurality of interchangeable mounting adapters which engage various components of the vehicle and secure the switch housing thereto. For example, one mounting adapter facilitates mounting of the switch housing on the turn signal lever. Another facilitates mounting to a flat surface and still another replaces a portion of the turn signal lever with the switch housing.
Abstract:
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, 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.
Abstract:
An assembly comprising: a seat (20) having a tubular frame part (40a) having a gas flow port (80); and an air bag module (36) comprising an inflator (50), the inflator including at least one exit port (56); wherein the inflator (50) is mounted within the frame part (40a) with the exit port (56) in fluid communication with the flow port (60). In one embodiment the inflator is slid into its desired position through the tubular frame part and in another the inflator (and a manifold 80') is received within an opening in the frame part.
Abstract:
An adjustable vehicle safety belt guide assembly (10) includes a base (28) and a movable carriage (30). The base (28) is mountable on a vehicle pillar (12) and includes a flexible cable (38), anchors (34, 36), and a plurality of lugs (40). The anchors (34, 36) are connectable with the pillar (12), and the flexible cable (38) is connected to the anchors (34, 36). The flexible cable (38) can follow the contour of the pillar (12). The lugs (40) are fixed to the flexible cable (38) to define adjustment positions for the carriage (30). The carriage (30) is movable along the flexible cable (38) and includes a lock mechanism (74) for releasably engaging the lugs (40).
Abstract:
An electronic system for monitoring the operation of a vehicle friction clutch assembly and for generating an indication when the clutch brake of the assembly is frictionally engaged is disclosed. The system generates an electrical signal which is representative of the rotational speed of the clutch brake. To accomplish this, a plurality of magnets or a plurality of radially outwardly extending teeth are secured to the clutch brake. A sensor is disposed near the clutch brake which is responsive to the passage of the magnets and teeth rotating thereby. The sensor generates an electrical pulse train signal having a frequency which is proportional to the rotational speed of the clutch brake. An electronic control circuit is provided for generating an indication when the value of the clutch brake rotational speed signal approaches zero, indicating that the clutch brake is frictionally engaged. A similar sensor be provided for determining the rotational speed of the flywheel of the friction clutch assembly. The control circuit compares the flywheel rotational speed signal with the clutch brake rotational speed signal and generates an indication when the values of the two signals are not equal or when they differ by more than a predetermined amount. Such a situation would occur when there is slippage in the friction clutch assembly which requires maintenance. The flywheel rotational speed signal can also be displayed separately as an analog or digital representation of the engine speed.
Abstract:
A cruise control servo cable assembly comprising a standard cable including a universal shielded cable end having means at its extremity for attachment to the appropriate one of a set of clevises or adapters provided with the cable assembly. The celvises are of a low cost stamped metal or molded plastic type and are appropriately marked so that by referring to an accompanying chart the installer can select the correct clevis for a particular vehicle and engine option and discard the remaining unused clevises. Means is provided for securely locking the selected clevis to the cable end. The shield encloses the cable end and moves back and forth with the clevis or adapter.
