<p>1,032,551. Adjustable seats. WILMOT-BREEDON Ltd. Aug. 21, 1962 [Aug. 25, 1961], No. 30651/61. Heading A4J. [Also in Division E2] Adjustable clamping means for a vehicle seat comprises two clamping members which are urged in opposite directions to limit positions and frictionally engage a movable member to clamp said member against movement in either direction, and manual adjustment means operated to move either one of the said members away from the corresponding limit position, and with it the movable member, at the same time as the other member is freed. The seat 1, Fig. 1, is supported by two parallel tubes 2 secured to it and movable in nylon slippers 9, 10 mounted in brackets 6, 7. An adjustable clamping means which operates on a further tube 13 mounted between the tubes 2 is mounted on a bracket 15 secured to the floor of the vehicle. The means comprises a U-shaped bracket 16 carrying nylon slippers 22, 23 similar to the slippers 9, 10. An inverted U-shaped bracket embraces bracket 16 and has a bearing pin 25 which passes through elongated apertures 24 in bracket 16 to permit limited movement of the lower part of bracket 18. Elongated bearing apertures 28 in bracket 18 also permit limited movement of the upper part of bracket 18 about a pin 17 in the bracket 16. The clamping members comprise members 29, 30 which are held apart at the bottom by turned in projections 33 on bracket 16 against the tension of a coiled spring 32. The upper ends of members 29, 30 have circular holes. through which the tube 13 passes, and come to rest in limit positions whereby the tube 13 is clamped against movement in either direction. When lever 26 is moved downwardly, pin 25 is pressed against the bottom end of clamping member 30 to grip tube 13 even tighter and the top part of bracket 18 moves to a position in which surface 27 engages the top end of clamping member 29 and releases its grip on tube 13 to allow it to be inched to the left, as viewed in Figs. 1 and 2, by the oscillation of the lever 26 in the downward position. Similarly, upward movement and oscillation of the lever 26 causes the seat to be inched forwardly.</p> |
