Abstract
Abstract The lower profile member of a seat slide carries a shoe made of an L-shaped member having two vertical brackets. A first bracket support a spindle on which is mounted a first latch having a lower end which normally bears on the shoe and which is returned to such a position by a coil shaped spring rigidly connected to the vertical bracket and to an upper part of the first latch. Two bearing elements carry a shaft having ends to which two sectors are fixed for supporting an abutment and a pin. The pin is adapted to act on a second latch mounted on the upper profile member for disengaging the first latch. The abutment is used for providing a limitation for a rearward stroke of the upper profile member with respect to the lower profile member.

A slide for a vehicle seat, including a back portion and a sitting portion, with a fixed return position system, said slide comprising: two lower profile members with a bottom portion and two upper profile members each one of said upper profile members slidably connected to one of said lower profile members, said lower profile members fixedly connected to a vehicle floor; each said lower profile member comprising a rack and each said upper profile member comprising a first spindle and a first latch with a toothing, said first latch pivotably mounted on said first spindle, each said upper profile member further having a leaf spring connected to said first latch for forcing into engagement said first latch with said rack; each said lower profile member further comprising a L-shaped shoe connected to said bottom portion, said shoe comprising a first and a second vertical bracket, said first vertical bracket having a second spindle; a second latch connected to said second spindle such that in an initial position a lower end of said latch rests on said shoe; a coiled spring connected with one end to said first vertical bracket and with the other end to an upper part of said second latch, said coiled spring forcing said lower end of said second latch into said initial position; each said upper profile member comprising a bearing element connected to a top portion of each said upper profile member; a shaft with ends connected to said bearing elements, each said end having a sector connected thereto, each said sector having an abutment and a pin, wherein said abutment acts on said first latch for disengaging said toothing from said rack in a disengagement position and said pin disengages said second latch against the force of said coiled spring from said initial position into an end position to allow a sliding movement of said upper profile members relative to said lower profile members; and said pin limiting a rearward movement of said upper profile member relative to said lower profile member when abutting said second vertical bracket of said shoe.

A slide for a vehicle seat, including a back portion and a sitting portion, with a fixed return position system, said slide comprising: two lower profile members with a bottom portion and two upper profile members each one of said upper profile members slidably connected to one of said lower profile members, said lower profile members fixedly connected to a vehicle floor; each said lower profile member comprising a rack and each said upper profile member comprising a first spindle and a first latch with a toothing, said first latch pivotably mounted on said first spindle, each said upper profile member further having a leaf spring connected to said first latch for forcing into engagement said first latch with said rack; each said lower profile member further comprising a L-shaped shoe connected to said bottom portion, said shoe comprising a first and a second vertical bracket, said first vertical bracket having a second spindle; a second latch connected to said second spindle such that in an initial position a lower end of said latch rests on said shoe; a coiled spring connected with one end to said first vertical bracket and with the other end to an upper part of said second latch, said coiled spring forcing said lower end of said second latch into said initial position; each said upper profile member comprising a bearing element connected to a top portion of each said upper profile member; a shaft with ends connected to said bearing elements, each said end having a sector connected thereto, each said sector having an abutment and a pin, wherein said abutment acts on said first latch for disengaging said toothing from said rack in a disengagement position and said pin disengages said second latch against the force of said coiled spring from said initial position into an end position to allow a sliding movement of said upper profile members relative to said lower profile members; and said pin limiting a rearward movement of said upper profile member relative to said lower profile member when abutting said second vertical bracket of said shoe.
Claim 3
Dependent Claim
57 words
A slide according to claim 1, further comprising a cable having one end attached to one of said sectors, said cable having the other end attached to a rotary portion of an articulation mechanism positioned between the sitting portion and the back portion of the vehicle seat, with a rotation of said sector achieved by said cable.
Claim 4
Dependent Claim
56 words
A slide according to claim 1, wherein said disengagement position and said end position are stabilized by passing said pin beyond a dead point of said sectors, and wherein said toothing again engages said rack and said initial position is resumed when the back portion of the vehicle seat is returned into a substantially upright position.
