Slide-guide for motor car seats

Claim 2

A slide-guide for a seat comprising: a rigid elongated guide with a channel-shaped cross-section having: a flat central portion, upwardly extending side walls, and borders extending outwardly from said side walls, the upper surface of said borders forming guide bearing races; an elongated slide having a central web spaced apart from said flat central portion of said guide, and having folded-under sides spaced from said borders and encompassing portions of said borders within their folds, the under surface of said slide facing said guide bearing races forming slide bearing races; and rolling bearings positioned in said races between said guide and said slide, whereby said bearings permit guided movement of said slide relative to said guide without contact between said slide and said guide.

Claim 3

The slide-guide as claimed in claim 1, wherein said rolling bearings comprise ball bearings; and including obstructions positioned in said slide bearing races to confine the travel of the bearings without restricting the travel of said slide.

Claim 4

The slide-guide as claimed in claim 1, wherein one of said borders has notches spaced along its length, and said slide includes an aperture in one of said folded sides capable of being aligned with one of said notches; said slide-guide further including a resilient rod coupled to said slide and having an engaging portion positioned in said aperture for releasable engagement with the sides of said notch, whereby movement between said slide and said guide is prevented.

Claim 5

The slide-guide as claimed in claim 3, including: a plate carried on said slide and coupling said resilient rod to said slide; and a handling rod rotatably coupled to said plate, said handling rod having a bent end positioned within a ring formed adjacent said engaging portion of said resilient rod, whereby rotation of said handling rod moves said engaging portion out of said slot and allows movement of said slide.

Claim 6

The slide-guide as claimed in claim 3, wherein one end of said resilient rod is coupled to said slide, said engaging portion is located between the ends of said resilient rod, and the other end of said resilient rod includes a catching hook for moving said engagement portion out of engagement with the sides of said slot.

Claim 7

A slide-guide for a seat comprising: a rigid elongated guide with a channel-shaped cross-section having: a flat central portion, upwardly and outwardly extending side walls, and borders extending outwardly from said side walls and parallel to said flat central portion, the upper surface of said borders forming guide bearing races, one of said borders having notches spaced along its length; an elongated slide having a central web parallel to and spaced apart from said flat central portion of said guide, and having folded-under sides spaced from said borders and encompassing portions of said borders within their folds, the under surface of said slide facing said guide bearing races forming slide bearing races, said slide having an aperture in one of said folded sides capable of being aligned with one of said notches; ball bearings positioned in said races between said guide and said slide, said bearings permitting guided movement of said slide relative to said guide without contact between said slide and said guide; and a resilient rod coupled to said slide and having an engaging portion positioned in said aperture for releasable engagement with the sides of said notch, whereby movement between said slide and said guide is prevented.

Claim 8

A slide-guide for a seat comprising: a rigid elongated guide with a channel-shaped cross-section having: a flat central portion, upwardly and outwardly extending side walls, and borders extending outwardly from said side walls and parallel to said flat central portion, the upper surface of said borders forming guide bearing races, one of said borders having notches spaced along its length; an elongated slide having a central web parallel to and spaced apart from said flat central portion of said guide, and having folded-under sides spaced from said borders and encompassing portions of said borders within their folds, the under surface of said slide facing said guide bearing races forming slide bearing races, said slide having an aperture in one of said folded sides capable of being aligned with one of said notches; ball bearings positioned in said races between said guide and said slide, said bearings permitting guided movement of said slide relative to said guide without contact between said slide and said guide; and a resilient rod coupled to said slide and having an engaging portion positioned in said aperture for releasable engagement with the sides of said notch, whereby movement between said slide and said guide is prevented.
