A plastic housing within the frame is recessed to accommodate the lever, cooperate with the frame to guide the tongue, and to provide spring reaction means for a push button spring mounted on a displaced integral push button seat formed in the lever. A cover with an access opening for the push button completes the assembly of frame, lever, housing and push button spring elements.

Abstract: A vehicle safety belt system including a retractor with a static loop snubber operative to normally freely pass webbing and to lock under predetermined belt load thereby eliminating occupant excursion incident to belt tension on the retractor side of the static loop snubber.

Abstract: An automobile compartment cover, for use in covering a compartment such as the windowed rear compartment of a hatchback or a station wagon type automotive vehicle, has a variable length elongated hollow cylindrical roller about which is rolled a flexible sheet member. At least one end of the roller includes a torsional spring to provide rotational tension on the cover; and compressional spring means to provide longitudinal tension in the roller.

Abstract: The structure disclosed includes an air supported transparent membrane which encloses a solar collector unit. The solar unit includes a solar collector element and two angled walls that support and position the element. The solar collector element receives and absorbs solar radiation and provides heat to a circulating fluid. The support walls extend forwardly and outwardly from the collector element and have reflecting facing surfaces to increase the amount of radiation falling on the element. The walls extend rearwardly of the element to define a chamber in which small rocks are stored to provide heat storage. The transparent membrane creates a greenhouse effect within the chamber defined by the membrane, increasing the operating temperature and thus the conversion efficiency of the solar collector element. Furthermore, the air supported membrane protects the solar collector unit from wind loading.

Abstract: The belt or webbing is wound on a spool, which is rotatably mounted between the spaced legs or sides of a generally U-shaped casing, and which has a ratchet wheel secured to one end thereof. A pawl is pivotally mounted in supporting slots in one or more of the casing sides for pivotal movement into and out of a belt-locking position in which one edge of the pawl engages a tooth of the ratchet wheel to prevent further rotation of the spool in a belt unwinding direction. A leafspring, which is secured at one end to the pawl, passes over the head of a pendulum member which is suspended from the pawl, and has a free end confronting and normally spaced from the wheel teeth. When sudden changes in vehicle speed cause the pendulum to swing, its head moves the leafspring to engage the wheel teeth, which, when the belt is unwound, swing the leafspring in a direction which causes the supporting pawl to be pivoted to its belt-locking position.

Abstract: An automobile rear compartment cover, for use in covering the windowed rear compartment of automotive vehicles such as a hatch back or a station wagon, has an elongated hollow cylinder roller about which is rolled a flexible sheet member and which has a spring loaded pivot device in one end.

Abstract: A table for a saw has three equal table segments supported on foldable legs. The three segments are spaced from one another by spacer elements and held in position by front and back longitudinal rails and nut and bolt combinations through the spacer elements. The spacer elements hold the table segments spaced from one another thereby defining first and second lateral slots within which the rail of a mitre gauge can ride. Four spacer elements are integral parts of a spacer bar. Each spacer bar has laterally spaced spacer elements and vertically spaced spacer elements thereby providing numerous accurately dimensioned spacing locations between adjacent table segments. The spacer elements and longitudinal rails in combination establish table element positioning and rigidity with respect to one another as well as established two longitudinal slots having a uniform predetermined width.

Abstract: A clip ejector rides along a track in a belt buckle. The track is molded onto the inner surface of the cover. The ejector is spring biased into a protracted position. A clip when inserted, contacts two shoulders on the ejector, forcing the ejector back until the clip is latched. On unlatching, the spring shoots the ejector forward causing the clip to be positively removed from the buckle. The track constitutes a rail having a longitudinal tubular groove. The ejector has a foot which extends up into the groove through a longitudinal slot in the rail. Two fins extend up from the ejector and ride on either side of the rail.

Abstract: A plurality of modular dual arch arrangements are aligned to provide the frame for a shelter. Each dual arch module constitutes first and second arches having their bases spaced from one another and leaning towards one another so that their crests rest against one another. The two arches are hinged to one another at their crests by a hinge. A fabric membrane is positioned over the arches and held in tension through various turnbuckles which attach the membrane to the bases which support the arches. A plurality of longitudinal fabric support bands are stretched longitudinally across the plurality of arches and held in tension to provide further support for the membrane.

Abstract: A safety on-off electrical switch for energizing an electrical apparatus. The safety switch is adapted to be mounted on the electrical apparatus, but may be separate therefrom. The safety switch includes a housing enclosing an on-off switch and an operating member, such as a key which is adapted for insertion into the housing to operate the on-off switch. The key has three different operative conditions relative to the housing. One is a key insertion and fully retraction position with no effect on the switch. The second is a neutral position in which the key is held in the housing, but cannot operate the switch; and the third is a switch operative position in which the key is movable from a fully inserted position to a partially retracted position to change the state of the switch from its off state to its on state.
