Abstract: A method for generating a pulse width modulation (PWM) signal, by a processor communicatively coupled to a system memory element, is provided. The method computes, by the processor, a coarse adjustment PWM output signal and a modified fine adjustment input signal, using a low speed clock rate; performs, by the processor, a fine adjustment to the coarse adjustment PWM output signal, using a high speed clock rate, based on the modified fine adjustment input signal; and generates an increased resolution PWM output signal, by the processor, based on the fine adjustment.

Abstract: An improved seat belt restraint system having a "comfort" feature for controlling tension in a shoulder belt. The comfort feature partially relieves tension exerted by the seat belt retractor on the vehicle occupant, yet prevents excess slack from developing in the shoulder belt which can negatively affect occupant protection performance of the restraint system. A webbing guide is provided which forms the upper anchorage of the shoulder belt of the restraint system. The webbing guide includes a sensing lever which contacts the seat belt webbing and is moved through various angular positions in response to tension applied on the shoulder belt. When the sensing lever is in an angular position corresponding to excess slack in the webbing, the webbing can pass freely through the guide loop and the retractor can freely retract webbing.

Abstract: A vehicle sensitive inertia safety belt retractor (VSI) equipped with push button actuated automatic locking device (ALR) preventing belt extraction when manually pressed with the belt extracted to a buckle engageable extent. Automatic restoration of VSI mode is effected in response to the increased diameter of belt webbing on the retractor spool upon retraction following buckle disengagement.

Abstract: An improved sun visor assembly, particularly adapted for use with motor vehicles. The visor assembly has a retractable auxiliary glare shield featuring snap-in assembly into the visor and includes features which prevent inadvertent removal of the glare shield. An internal or external edge cap is provided which forms an outer edge of the visor and guides the auxiliary glare shield. The edge cap engages and secures the edges of the visor outer board around the opening for the auxiliary glare shield. On one preferred embodiment, an internal split end cap is provided, each half of which engages one of the edges of the outer board by means which allow exact location to allow the end cap halves to snap together permanently after being stitched to the wrapped-around soft trim and outer board. The visor thus has a normal appearance with the end cap which provides a firm opening for the glare shield, while the end cap being invisible.

Abstract: A dual spool seat belt retractor includes a comfort mechanism actuated by limited protraction of one belt relative to the other to provide a predetermined amount of slack in the one belt. A comfort limiting mechanism is drivingly coupled by a gear train to both the first and second retractor spools to disengage the comfort mechanism in response to relative rotation between the first and second spools caused by protraction of the one belt to an extent exceeding the limited protraction employed to actuate the comfort mechanism so as to allow retraction of the belt by the rewind spring. Slack in the belt in excess of the predetermined amount is thereby prevented. The comfort mechanism is also disengaged by the comfort limiting mechanism when the belts are unbuckled to allow full retraction of both belts.

Abstract: An improved visor assembly for motor vehicles is disclosed which includes one or more retractable glare screens which are integrated with the visor structure such that they can be extended and retracted from the visor as needed. The glare screens are preferably made from a transparent tinted material which reduces the intensity of bright lights or glare which the driver may be exposed to. The glare screens are guided for retracting movement through using slot followers which travel in elongated guide slots formed by the visor center board member. Clearance slots are formed along the perimeter edge of the visor by using elongated reinforcement members. The visor according to this invention can be produced economically and enables the glare screens to be extended and retracted without binding.

A resilient biasing member, which is preferably a leaf-type spring, is received within the sleeve member for resiliently biasing the rod member laterally against the interior surface of the sleeve member in order to provide a frictional relative rotational engagement between the rod member and the sleeve member.

Abstract: A hinge assembly is disclosed which is particularly well suited for vehicle accessory applications, such as for pivotally interconnecting vanity doors with vanity housing structures for example. The hinge assembly, which is also applicable for other applications, includes a pivot means pivotally interconnecting first and second members for relative rotational movement about a longitudinal axis, with a cam on the first member protruding in a generally lateral direction to engage a resilient biasing means on the second member. The resilient biasing means, which is preferably a leaf spring, is slidably engaged and resiliently deflected by the cam on the first member and exerts a resilient biasing force on the cam in a generally lateral direction, generally toward the pivot axis.

Abstract: A preferred illuminated vehicle accessory according to the present invention includes a light-emitting and light-conducting light bar, an electric light source operatively associated with the light bar, and an electrical connection device for electrically connecting the light source with a source of electrical current on the vehicle. The light bar is adapted to be interconnected with the vehicle accessory, and a light-directing apparatus is provided for directing the light emitted from the light bar toward at least one predetermined portion of the vehicle. The light bar preferably includes an elongated rod member composed of a light-conducting material, such as an acrylic material for example, that is at least semi-transparent. In various forms of the invention, the light bar can be located either on an internal surface of the vehicle accessory or on an exposed surface of the vehicle accessory.

Abstract: An accessory cover apparatus for selectively covering or exposing an open vehicle compartment includes an adjustable mounting assembly interconnectable with the vehicle for mounting and supporting the cover apparatus generally adjacent the compartment opening at an intermediate longitudinal position between the compartments ends. The cover apparatus includes a first cover member that is longitudinally movable between retracted and extended positions. A second cover member protrudes generally in an opposite direction from that of the extended first cover member and is pivotally movable between a closed position and an open position. Preferably, the cover apparatus according to the present invention further includes an open enclosure member disposed beneath the second cover assembly for defining a storage sub-compartment, with the second cover member substantially closing off the sub-compartment when in its closed position and providing access to the interior of the sub-compartment when in its open position.
