Abstract: An infinitely adjustable linear locking assembly for vehicle seats is disclosed which includes a movable elongated element defining a longitudinal axis. First and second roller ball assemblies coaxial with the elongated element are provided, which assemblies have at least two substantially equidistantly spaced apart roller balls surrounding the elongated element. First and second roller ball housings contain the first and second roller ball assemblies, respectively. The housings are coaxial with the elongated element and have internal wedging surfaces for wedging the roller balls between the internal wedging surfaces and the elongated element. A rotatable locking member is provided adjacent to each roller ball assembly, with the locking member being coaxial with the moveable element and rotatable about the elongated element.

Abstract: A backlash reduction mechanism for incorporation into a selectively latchable vehicle seat hinge assembly for reducing the backlash between a plurality of interconnecting movably operative latch members positioned seriatim with respect to one another in the vehicle seat hinge assembly and method for producing the mechanism are disclosed. The latch members are retained in interposed relation between first and second hinge plates. One of the latch members, a manually operable lever means, is rotatably mounted about a second pivot axis on an eccentrically operative rotatably adjustable backlash reduction means, which is in turn rotatably mounted on the first and second hinge plates about a first pivot axis.

Abstract: A vehicle seat hinge assembly having first and second generally opposed and parallel hinge plates rigidly connected in spaced relation to one another, and a central third hinge plate partially sandwiched between the first and second hinge plates is disclosed, together with a process for assembling the hinge assembly. The third hinge plate is connected in hinged relation to the first and second hinge plates by a pivot pin, which pin has a longitudinal axis and first and second shoulder portions extending in opposite axial directions from a centrally disposed annular hub portion, which shoulder portions each contain an amount of plastically deformable shoulder material.

Abstract: A vehicular seat back recliner hinge comprises first and second hinged members that are mutually rotatably arranged about a common pivot. The first member has a gear rack arranged thereon which is adapted to be engaged by a pinion spur gear. The pinion spur gear is fixed on an adjacent ratchet wheel spur gear in mutually dependent rotatable relation about a common concentric shaft secured on a second hinged member. A selected one of the above-mentioned shaft and pivot are eccentrically mounted on a rotatable bushing arranged on a corresponding one of the members. The bushing is operable to selectively position the pinion gear and the rack in first mutually proximal and second mutually spaced positions.

Abstract: A diaphragm pump having a reciprocating piston, a rotatable cam canted and engaging the piston, and a diaphragm secured to a plunger stem by a screw rotatable relative to the stem. The plunger stem extends into a bore in the piston, the piston bore and plunger stem having a matching configuration preventing rotation of the plunger stem relative to the piston when the diaphragm securing screw is loosened. The piston end engaging the cam is formed as a spherical section positioning the line of engagement with the cam closely adjacent the axial center of the piston, to reduce side thrust.

Abstract: The carpet cleaning device of this invention includes a liquid application means, liquid removal means and carpet brushing means. A reciprocating motion is provided to a pivoted brush by means of a rotary shaft having an oblique crank portion carrying a bearing whose outer race is connected to the brush. The shaft axis, center line of the bearing, and the brush pivot axis all intersect at a common point thus transforming rotary motion of the shaft to an arcuate, reciprocating motion of the brush.
