Seating part of a vehicle seat
View Patent ↗A vehicle seat including a seat member, having a seat face and two lateral members. The seat face may be provided between the lateral members in an integral manner. The vehicle seat may further include a height adjuster for adjusting a height of the seat face, and the height adjuster may be integrated in the lateral members. Each of the lateral members may have a recess, the shape of which may change during the height adjustment. The height adjuster may include a drive element. The drive element may include a rotor with helical slots. The lateral members may have projections provided which cooperate in a positive-locking manner with the helical slots. During rotation of the rotor, the projections may be moved away from each other or toward each other. Height adjustment of the seat face may be carried out.
1. A vehicle seat comprising a seat member, having a seat face and two lateral members,
wherein the seat face is provided between the lateral members in an integral manner;
wherein the vehicle seat further comprises a height adjuster for adjusting a height of the seat face, wherein the height adjuster is integrated in the lateral members;
wherein each of the lateral members has a recess, a shape of which changes during the height adjustment;
wherein the height adjuster has a drive element;
wherein the drive element comprises a rotor with helical slots; and
wherein on the lateral members projections are provided which cooperate in a positive-locking manner with the helical slots, whereby during rotation of the rotor the projections are moved away from each other or towards each other, and whereby the height adjustment of the seat face is carried out.
2. The vehicle seat as claimed in claim 1 , wherein at least one resilient element is provided on each lateral member in an integral manner.
3. The vehicle seat as claimed in claim 2 , wherein at least two resilient elements are provided on each lateral member.
4. The vehicle seat as claimed in claim 3 , wherein the resilient elements have different resilient characteristic lines or different resilient excursions to absorb different loads in dependence of a location relative to a seat occupant and in dependence of forces in a crash situation.
5. The vehicle seat as claimed in claim 2 , wherein each lateral member has a resilient link in an integral manner, which is provided with a backrest connection in an integral manner.
6. The vehicle seat as claimed in claim 1 , wherein the drive element has a periphery that can be changed in a reversible manner by cooperating with components of a periphery of the recess to consequently change the height of the seat face.
7. The vehicle seat as claimed in claim 6 , wherein the drive element cooperates with the recess and changes a shape thereof.
8. The vehicle seat as claimed in claim 7 , wherein the height adjustment has a second drive element which changes a shape of a second resilient element.
9. The vehicle seat as claimed in claim 6 , wherein the drive element cooperates with a positive-locking means, which are provided on the lateral member.
