1. A car seat comprising:
- a central spring system (3) with longitudinal spring elements having an adjustable resistance force, wherein the resistance force is adjusted by a rotating driving gear that rotates a transverse wave, the transverse wave linked to one end of the spring elements and an opposite end of the spring elements fixed on a rear transverse spar; and
side reinforcements extending in the direction of travel each with an upper edge region, wherein the position of the side reinforcements or of the upper edge regions changes depending on the resistance force of the central spring system (3) so that an increase in the resistance force of the central spring system (3) corresponds to a higher position of the upper edge regions, wherein the position of the side reinforcements is changed by coupling the rotation of the transverse wave with a gear unit.

Abstract
A car seat having a seat part and a central spring system for the seat part. The central spring system can be adjusted to vary the hardness of the seat part. Additionally, the car seat is provided with side reinforcements on the seat part that extend in the traveling direction, whose position or the position of their upper edge regions is adjustable in accordance with the hardness of the spring system of the seat. The adjustment of the spring system is such that a greater degree of hardness corresponds to a higher position of the upper edge regions of the side reinforcements.

9. A car seat comprising:
- one or more spring support elements connected to a rotating member, wherein rotation of the rotating member adjusts the resistance force of the spring support elements; and
side support members with an upper edge region extending out from the seat, and the position of the side support members changes as the resistance force of the spring support elements is adjusted, the side support members move in toward the seat as resistance force in the spring support elements increases, wherein the side support members include a rotating shaft coupled to a bevel gear in union with the rotating member. - View Dependent Claims (10)
