Abstract

The invention relates to a vehicle seat comprising: a seating portion having a seat frame with a pair of frame members and a cross member arranged between the pair of frame members; a seat base for supporting the seating portion; a height-adjustment mechanism for adjusting the height of the seat frame with respect to the seat base, and comprising at least one height-adjustment link; and an easy-entry mechanism for displacing the seating portion with respect to the seat base at least along a longitudinal axis between a use position and an easy-entry position, and comprising at least one easy-entry link being pivotably mounted on the seat base and pivotably connected with the height-adjustment link, the height-adjustment link connecting the easy-entry link with the cross member.

First claim

What is claimed is:

1. A vehicle seat comprising:
a seating portion having a seat frame with a pair of frame members and a cross member arranged between the pair of frame members;
a seat base for supporting the seating portion;
a height-adjustment mechanism for adjusting a height of the seat frame with respect to the seat base, and comprising at least one height-adjustment link;
an easy-entry mechanism for displacing the seating portion with respect to the seat base at least along a longitudinal axis between a use position and an easy-entry position, the easy-entry mechanism comprising at least one easy-entry link being pivotably mounted on the seat base and pivotably connected with a respective height-adjustment link, the height-adjustment link connecting the easy-entry link with the cross member;
a backrest portion pivotably supported on the seating portion; and
a recliner pivotably connecting the backrest portion with the seating portion, wherein the recliner includes a first recliner part fixedly connected with a frame member of the seat frame and a second recliner part fixedly connected to a backrest frame of the backrest portion, wherein the first recliner part and the second recliner part are rotatably mounted to one another.

2. The vehicle seat of claim 1 , wherein the height-adjustment link may be rotated with respect to the seat base for effecting a height adjustment of the seating portion.

3. The vehicle seat of claim 1 , wherein the height-adjustment link is fixed to the cross member.

4. The vehicle seat of claim 1 , wherein the cross member is pivotally mounted on each of the pair of frame members.

5. The vehicle seat of claim 1 , wherein the cross member is a rod or a stamped bracket.

6. The vehicle seat of claim 1 , wherein the backrest portion may be adjusted with respect to the seating portion by means of the recliner without displacing the seating portion with respect to the seat base.

7. The vehicle seat of claim 1 , further comprising at least one arm being pivotably mounted on the seat base and pivotably connected with the frame member.

8. The vehicle seat of claim 7 , wherein the arm is pivotably mounted on the seat base at a first position and the easy-entry link is pivotably mounted on the seat base at a second position, the first and second positions being spaced apart from one another.

9. The vehicle seat of claim 7 , further comprising a backrest portion pivotably supported on the seating portion, wherein a recliner pivotably connects the backrest portion with the seating portion, and wherein the easy-entry link is located closer to the recliner than the arm.

10. The vehicle seat of claim 1 , the height-adjustment mechanism comprising a pair of height-adjustment links, and the easy-entry mechanism comprising a pair of easy-entry links.

11. The vehicle seat of claim 1 , further comprising a guide rail assembly mounted or mountable on a vehicle floor, for adjusting a longitudinal position of the seating portion with respect to the vehicle floor.

12. The vehicle seat of claim 11 , further comprising an interlock mechanism locking the easy-entry mechanism in the use position when the vehicle seat is arranged in a full-forward position of the guide rail assembly.

13. The vehicle seat of claim 1 , wherein the easy-entry mechanism further comprises a releasable latch or cam lock for restricting and releasing a pivoting motion of the easy-entry link with respect to the seat base.

14. The vehicle seat of claim 13 , wherein the latch or cam lock is releasable by at least one of pivoting a backrest portion with respect to the seating portion, by operating a handle, and by adjusting a longitudinal position of the seating portion with respect to the vehicle floor.

15. The vehicle seat of claim 13 , wherein a bolt or striker wire is mounted on the easy-entry link, and the latch or cam lock may be engaged with the bolt or striker wire for locking the easy-entry link on the seat base.

16. The vehicle seat of claim 1 , wherein the easy-entry mechanism further comprises a spring pre-tensioning the vehicle seat into the easy-entry position, or a drive motor for driving the vehicle seat into the easy-entry position.

17. A vehicle seat, comprising:
a seating portion having a seat frame with a frame member;
a seat base for supporting the seating portion;
a first link having a first end and a second end, the first end being mounted on the seat frame by means of a pivot bearing, so as to be pivotable with respect to the frame member;
an easy-entry mechanism for displacing the seating portion with respect to the seat base at least along a longitudinal axis between a use position and an easy-entry position, and comprising a second link pivotably mounted on the second end of the first link by means of a pivot bearing and pivotably mounted on the seat base;
a backrest portion pivotably supported on the seating portion; and
a recliner pivotably connecting the backrest portion with the seating portion, wherein the recliner includes a first recliner part fixedly connected with a frame member of the seat frame and a second recliner part fixedly connected to a backrest frame of the backrest portion, wherein the first recliner part and the second recliner part are rotatably mounted to one another.
