In particular, the invention relates to a slide rail for a vehicle seat, comprising:

• First and second profiles slidably mounted with respect to each other in a longitudinal direction, the first and second profiles defining an interior therebetween,
• A lock disposed in the interior and extending along the longitudinal direction between a fixing portion defined with respect to the first profile and a locking portion, the locking portion being displaceable in a vertical direction perpendicular to the longitudinal direction between a locking position in which the locking portion is engaged is engaged with the second profile such that the first profile is locked with respect to the second profile, and an unlocking position in which the locking portion is spaced or disengaged from the second profile such that sliding of the first profile with respect to the second profile second profile is enabled, wherein the locking portion is resiliently biased toward the locking position,
• An operating lever extending along the longitudinal direction and pivotally mounted with respect to the first profile about an axis extending in a transverse direction, perpendicular to the longitudinal and vertical directions, the operating lever having a free end formed around the locking portion from the locking position to the unlocking position.

Slide rails of this type are known from the documents FR 2 767 096 A1 and WO 2007/095762 A1 ,

However, the known slide locks have a complex structure to ensure proper positioning of the operating lever with respect to the lock and thus to ensure a satisfactory operation of the lock can.

The invention aims to overcome or mitigate the aforementioned drawbacks.

To this end, the invention proposes a slide rail of the aforesaid kind in which the lock comprises an elastically deformable metallic tab extending along the longitudinal direction between a first end forming the fixing portion and a second end forming the locking portion, a plastic part connected to the second end of the tab or is made in one piece, wherein the part carries an open receptacle according to the longitudinal direction and is adapted for receiving the free end of the actuating lever.

Thus, the receptacle formed in the plastic part ensures easy positioning with accurate adjustment of the free end of the operating lever, without the need to resort to complex configurations of offset elastic tongues as used in known slide rails. The locking structure is therefore simplified. Furthermore, the positioning of the free end of the operating lever, carried out immediately at the level of the locking portion, located at one of the ends of the tab on which the free end acts, to ensure proper operation of the lock or the lock.

Furthermore, the dimension in the longitudinal direction can be reduced due to the configuration of the locking portion and the part, thus simplifying the provision and transport of the lock.

The provisions also make it possible to reduce the amount of metal used for locking and thus to provide a reduction in terms of weight and cost.

They also allow a tab to be provided which has a simplified geometry for which it is easier to provide satisfactory quality against manufacturing defects and deterioration during deployment and transportation. Furthermore, the metallic tab can be made by embossing or flattening by means of a press, which shows a simplified structure, whereby a lower pressure effect can be used.

In order to adjust the position of the seat must have the locking portion of the lock 50 are offset to an unlocked position or unlocking position, in which the cantilevers 60 spaced apart along the vertical direction Z of the notches 24 , To the tab 51 the lock 50 deform to displace the locking portion along the vertical direction Z includes the slide rail system 5 also a traverse 6 of general U-shape, comprising two branches of actuation or branches or levers 7 extending in parallel and each extending from a base 8th to a free end 9 , Each of the operating levers 7 is arranged in the interior of one of the slide rails 10 passing through the opening 57 of the transversal section 53 the tab 51 , where the free end 9 is arranged in the recording 72 of the part 70 , The operating lever 7 thus extends along the longitudinal direction X, being elastically biased by the tab 59 of the second section 54 the tab 51 towards the Anlenkungsrand 58 the opening 57 of the transversal section 53 , The operating lever 7 can thus at the Anlenkungsrand 58 with reference to the movable profile 11 pivoting about an axis, extending along the transverse direction Y. As shown in FIG 4 get the Lateralwandungen 73 the recording 72 in contact with the free end 9 of the operating lever 7 , on both sides in this regard along the transverse direction Y. The free end 9 of the operating lever 7 can thus lateral indentations 13 in which the beads 75 intervene to the free end 9 of the operating lever 7 to pinch. The base 71 and the edge 77 the recording 72 get in touch with the free end 9 of the operating lever 7 , this side and beyond along the vertical direction Z. The free end 9 of the operating lever 7 is thus abutting or abutting along the transverse and vertical directions Y and Z. In order to ensure abutment according to the longitudinal direction X, the actuating lever comprises 7 a notch 64 , a stop surface 65 comprising, formed at a distance from the free end 9 along the longitudinal direction X and directed in a direction opposite or opposite to the free end 9 , This notch 64 is designed so that the latch finger 63 of the second section 54 the tab 51 can intervene there and to come into contact with the stop surface 65 at a distance from the transverse wall 76 of the part 70 with which the free end 9 otherwise come into contact. During an imposition in the direction of the arrow F of 3 , exercised on the basis 8th the traverse 6 by a user, the longitudinal position of his seat 1 wants to adjust, the operating lever pivots 7 against the hinge edge 58 of the transversal section 53 the tab 51 , This puts the free end 9 of the operating lever 7 the locking portion of the lock 50 along the vertical direction Z towards the base 12 fixed or rigid profile 12 , such that the cantilevers 60 from the detents 24 be released or disengaged. To the displacement of the lock or the lock 50 in the interior of the slide rail 10 to restrict, and in particular to a touch of the lock 50 with the base 15 To avoid are the beak or the tip 80 and the stop 78 formed at an appropriate distance to contact the outer surface of the base 30 when the locking portion is in the unlocked or unlocked position. When the loading is released or released, the locking portion of the lock becomes 50 returned or brought back to the locking position or locked position, wherein the cantilevers 60 enter into new catches 24 of the fixed profile 12 through windows 38 of the moving profile 11 to the seat 1 positionally blocking.
