Abstract

A vehicle seat ( 1 ) has an easy-entry module ( 6 ). A backrest ( 2 ) is adjustable relative to a seat part ( 3 ) between at least one comfort position (P 1 ) and at least one easy-entry position (P 3 ). The backrest ( 2 ) is, together with the seat part ( 3 ), arranged so as to be longitudinally displaceable by way of rails ( 4 ) along a movement travel (W) over a longitudinal adjustment range (L) at least between two seat positions (S 1.1 to S 1. n ). To limit the movement travel (W), at least one switchable abutment ( 10 ) is provided in the region of the rails ( 4 ). The backrest ( 2 ) is, at a predefined seat position (S 2 ), settable upright by way of the switchable abutment ( 10 ) from the easy-entry position (P 3 ) into the comfort position (P 1 ) and lockable to the seat part ( 3 ) in the predefined seat position (S 2 ).

First claim

What is claimed is:

1. A vehicle seat comprising:
a seat part;
a backrest;
rails;
an easy-entry module, wherein the backrest is adjustable relative to the seat part between at least one comfort position and at least one easy-entry position, the backrest is, together with the seat part, arranged so as to be longitudinally displaceable by way of the rails along a movement travel over a longitudinal adjustment range at least between two seat positions;
at least one switchable abutment, to limit the movement travel, provided in a region of the rails; and
a counterpart abutment at one of the rails, wherein:
with the seat being moved out of one of the seat positions and the backrest being moved, from the comfort position into the easy-entry position, the switchable abutment is configured to override the counterpart abutment causing the switchable abutment to switch into an end position; and
with the seat being moved in return, from the easy-entry position into the comfort position, the seat is stopped at the switchable abutment and with the backrest being moved in return, from the easy-entry position into the comfort position, the backrest is settable upright from the easy-entry position into the comfort position by way of the switchable abutment, upon the switchable abutment striking against the counterpart abutment, switching out of the end position and, whereby the seat is subsequently movable over the longitudinal adjustment range and lockable to the seat part in one of the seat positions.

2. A vehicle seat according to claim 1 , wherein the counterpart abutment is comprised by one of the rails or is formed at one of the rails in the region of the rails ahead of a rearmost seat position.

3. A vehicle seat according to claim 2 , wherein the switchable abutment comprises at least one abutment pawl which has an abutment surface which corresponds with the counterpart abutment.

4. A vehicle seat according to claim 2 , wherein the counterpart abutment is arranged on a fixed abutment rail.

5. A vehicle seat according to claim 1 , wherein the seat part is, after the locking of the backrest to the seat part in one of the seat positions, displaceable over an entirety of the longitudinal adjustment range.

6. A vehicle seat according to claim 1 , further comprising at least one switching element arranged between the switchable abutment and the easy-entry module.

7. A vehicle seat according to claim 6 , wherein the switching element acts on the switchable abutment to switch the switchable abutment.

8. A vehicle seat according to claim 6 , wherein the switching element comprises a spring arrangement whereby the switchable abutment is switchable at the one of the seat positions.

9. A vehicle seat according to claim 1 , wherein the switchable abutment is arranged within and/or outside the rails.

10. A vehicle seat according to claim 1 , wherein the switchable abutment is arranged on a movable part of at least one of the rails or on a frame element of the seat part.

11. A vehicle seat comprising:
a seat part;
a backrest;
rails, wherein the backrest is, together with the seat part, arranged so as to be longitudinally displaceable by way of rails along a movement travel over a longitudinal adjustment range at least between two seat positions;
an easy-entry module, wherein the backrest is adjustable relative to the seat part between at least one comfort position and at least one easy-entry position;
at least one switchable abutment, to limit the movement travel, provided in a region of the rails wherein:
with the backrest being moved from the comfort position into the easy-entry position, the switchable abutment is configured to override an end of the rails and to switch into an end position; and
with the backrest being moved in return from the easy-entry position into the comfort position, the switchable abutment strikes the end of the rails to switch out from the end position and the backrest is settable upright from the easy-entry position into the comfort position upon which the seat is movable over the longitudinal adjustment range and is lockable in one of the seat positions.

12. A vehicle seat comprising:
a seat part;
a backrest;
a backrest pivot adjuster connected to the seat part and the backrest for locking a pivot position of the backrest relative to the seat part to provide a backrest locked pivot state and for unlocking a pivot position of the backrest relative to the seat part to provide an unlocked pivot state;
rails, wherein the backrest is, together with the seat part, connected to the rails and is longitudinally displaceable by the rails along a movement travel over a longitudinal adjustment range at least between two vehicle seat positions;
a rail locking means for locking the vehicle seat in a vehicle seat position along the longitudinal adjustment range;
an easy-entry module connected to the rails and operatively connected to the backrest, wherein the backrest pivot adjuster is coupled to the easy-entry module for the unlocking of the rail locking means, wherein the vehicle seat is adjusted forward into the easy-entry vehicle seat position and the backrest is pivotable forward from a comfort backrest position to an easy-entry backrest position; and
at least one switchable abutment provided in a region of the rails and connected to the easy-entry module, wherein:
with the backrest in the easy-entry backrest position, the switchable abutment is configured to pass an end of the rails causing the switchable abutment to switch into an end position as the vehicle seat is moved into the easy-entry vehicle seat position; and
with the switchable abutment past the end of the rails, a return movement of the vehicle seat, out of the easy-entry vehicle seat position, causes the switchable abutment to strike the end of the rails to switch out from the end position, whereby the backrest is settable upright from the easy-entry backrest position into the comfort position and switch to allow uprighting locking with the backrest pivot adjuster and the vehicle seat is movable over the longitudinal adjustment range and is lockable in one of the seat positions.

13. A vehicle seat according to claim 12 , wherein the end of the rails comprises a counterpart abutment in the region of the rails ahead of a rearmost seat position.

14. A vehicle seat according to claim 12 , wherein the seat part is, after the locking of the backrest to the seat part in said one of the seat positions, displaceable over an entirety of the longitudinal adjustment range.

15. A vehicle seat according to claim 12 , further comprising a switching element forming the connection between the switchable abutment and the easy-entry module, wherein the switching element comprises a spring arrangement switching a state of the switchable abutment at the one of the seat positions.
