Abstract

THE SEAT SLIDE INCLUDES AN INTERIOR SLIDE ELEMENT 15 WITH A CROSS-PROFILE IN A TOP HAT RECEIVED IN AN EXTERIOR SLIDE ELEMENT 16 HAVING CORRIDORS FACING THE INTERIOR WHICH RECEIVE RAILS OF PLASTIC MATERIAL 23. THE RAILS WITH SLOTS IN WHICH THE SLIDES OF THE INNER SLIDE MEMBER ARE ENGAGED FOR SLIDING TO ENSURE A SILENT AND SOFT SLIDING WITHOUT NOISE OF SCRAP.

Description

The invention relates to seat guides for adjusting the

  front and rear of motor vehicle seats and it carries a type of seat slide which comprises elongated interior and exterior elements arranged to engage one inside the other for a relative displacement of flow between ce 8 elementso Two slides are provided for each seat so as to avoid twisting or other deformation of the seat chassis and a releasable locking means is provided, either on each seat slide or on one of the two seat slides, the locking means which can be released being movable between a release position in which a relative sliding movement is allowed so that in service the adjustment of the position of the vehicle seat can be carried out and a locking position in which this relative sliding movement is prevented A seat slide of the above type is designated hereinafter

  like a seat slide of the stated type.

  In a form of seat slide of the stated type, rolling bearings are carried by the inner element to cooperate with a flat bearing surface of the outer element, the rolling bearings facilitate the relative sliding movement between the sliding elements Such arrangements of rolling bearings have a

  disadvantage in that, unless all parties are consti.

  guardrails of the slide are established with very narrow manufacturing tolerances, there can be either an irregular sliding effect, or a noise of scrap of the bearings We therefore already proposed to use surfaces of

  carried in plastic and, in such a project, a coating

  plastic mold was molded on the inner slide element Although this arrangement avoided the problems of scrap noise and irregular sliding effect, the cost of establishing the molded plastic coating was

  significantly higher than the cost of rolling bearings.

  An object of the present invention is therefore to establish an improved form of seat slide of the stated type which makes it possible to avoid the problems recalled above without

  incur higher costs.

  dant outward of 161 ée 6 t int rio slide and in which a rail of nt & ie plastic is mounted in each of these U-shaped corridors, each plastic rail itself comprising an interior corridor which engages

  the corresponding rim for its sliding.

  The internal sliding element preferably has a top shaped cap profile transversely and it carries, between its ends the trigger blocking means when it is provided, this blocking means is in the form of a spring pawl disposed to selectively engage in cutouts formed in one of the walls of one of the U-shaped corridors of the external slide elemento The pawl is preferably mounted to pivot on a support attached to the internal slide element and may have two teeth so that the locking engagement is effected with two of the cutouts in said wall of the U-profile. In the case of a combination of gllasière and seat in which each of the two slides has a locking means can be triggered, an actuation handle is preferably attached to the locking pawl of one of the two slides and a transverse shaft mechanism connects the pawls of the two slides so that these pawls s moved in unison between their latching and latching positions by being individually recalled by spring

to their latching positions.

A coupling element 33 is provided at each extr

  half of the tube and the two coupling elements 33 come together

  chent with shapes in cooperation on the locking pawls 28, so that the oliquets 28 rotate to '1 tunison either under the action of the respective springs 30, or against the action of these springs 30 The rotation of the eliquets 28 is performed by the actuation handle 12 attached to the click 28 of the slide 11, the actuation handle 12 oomprenan

  a sleeve 34 which mounts on a part of the corresponding ratchet

  laying 28 and is then made integral As the two slides 10 and 11 are interconnected by the transverse shaft 32, it is obviously sufficient with a single lever

command 12.

  The heads of the bolts 22 used to attach each external slide element 16 to the floor of the vehicle act as stops and cooperate with ears 35 formed

  by cutouts in one of the edges of the internal element

  associated slide laughter and folding of these ears towards

  the interior In operation, the interior sliding element

  15 of each slide is free to move inside

  inside of the outer slide element 16 between two limit positions in the first of which 12 one of the ears 35 abuts against one of the bolts 22 while, in the second of these positions, the other ear 35 abuts against

the other bolt 22.
