A sleeve-like bearing is positioned between the first and second members. The bearing has an original pre-cured shape that fits loosely into the clearance space between the members during assembly, and further has lubricious bearing material to facilitate smooth extension of the members, but further is made at least in part of a material that when cured expands to a size and shape that takes up an increased percentage of the clearance space. By this arrangement, the bearing can be easily positioned in the clearance space, but after thermal curing the bearing expands to reduce wobbling and looseness between the first and second members.

A second upper rail included in the second slide rail has in its lower portion a first slide portion identical with that of a first upper rail in the first slide rail as well as a second slide portion fixed on the opposite side of the first slide portion. That is, the second slide rail is constructed such that its upper rail is engageable with its lower rail at the two positions thereof, with the result that the second upper rail of the second slide rail is able to share a removing load by the seat belt anchor at the first and second slide portions.

  • Patent number: 4756503
    Abstract: A slide device for use in an automotive seat which is capable of adjusting the positions of the seat forwardly and backwardly. In the slide device, an upper rail provided on the side of the seat is slidably mounted via a slider to a lower rail provided on the side of floor of the automobile. The slider comprises a plate spring which is provided with a plurality of projected portions in the portions thereof where the slider is brought into contact with the upper rail. That is, the projected portions of the plate spring prevents the generation of play of the upper rail in the vertical direction as well as in the right and left direction thereof.

  • Patent number: 4725032
    Abstract: A vehicular seat slide adjuster has a lower rail fixed to a vehicle body and an upper rail to which a seat cushion frame is attached, the upper and lower rails being engaged with each other in sliding relation. The lower rail includes a vertical wall portion, upper and lower horizontal wall portions projecting from respective edges of the vertical wall portion, and flange portions extending downwardly from respective ones of the horizontal wall portions. The upper rail includes a vertical wall portion opposing the vertical wall portion of the lower rail in spaced relation, horizontal wall portions opposing the horizontal wall portions of the lower rail in spaced relation, and flange portions opposing the flange portions of the lower rail.

  • Patent number: 4711589
    Abstract: The present invention provides a seat adjuster slide mechanism and method of utilization of the same which is infinitely horizontally adjustable. The seat adjuster slide uses a vertically actuated cam. In its preferred embodiment two opposite surfaces of the cam are utilized and the cam "floats" to equalize the cam angle. Therefore relative movement between the sliding members of the seat adjuster increase the locking force. The present invention also provides a seat adjuster master/slave slide assembly which utilizes one conventional non-infinitely variable type slider mechanism for the master slider in combination with the vertically actuated cam type slave slider adjuster. Use of the vertically actuated cam slider for the slave slider eliminates the prior alignment problem experienced when using a slave adjuster which is non-infinitely variable.
