## CPC

- B60N 2/42: the seat constructed to protect the occupant from the effect of abnormal g-forces, e.g. crash or safety seats (for protecting children B60N2/26; arm-rests B60N2/75; head-rests B60N2/888)
- B60N 2/2869: {rotatable about a vertical axis}
- B60N 2/2884: {with protection systems against abnormal g-forces}
- B60N 2/2893: {coupled to the seat sub-frame}
- B60N 2/4235: {transversal}
- B60N 2/42736: {of the whole seat}
- B60N: SEATS SPECIALLY ADAPTED FOR VEHICLES; VEHICLE PASSENGER ACCOMMODATION NOT OTHERWISE PROVIDED FOR

## Abstract

The present invention relates to a child safety seat (1) comprising at least a head section (3), a back section (4) and a sitting section (5), where a base frame (7) is connected through pivot means (9) to the sitting section of the child safety seat, the pivot means (9) preventing the sitting section (5) from separating from the base frame (7), thereby providing a fixed connection between the sitting section (5) and the base frame (7) under normal utilization of the child safety seat (1), but allowing the head section (3), back section (4) and sitting section (5) to rotate sideways about a pivot axis in the event of a collision.

## Claims

### Claim 1

A child safety seat (1) for use in a vehicle, the child safety seat comprising at least a head section (3), a back section (4) and a sitting section (5), a base frame (7) having a lower surface resting on a sitting portion of a vehicle seat (2) and being connected to the child safety seat (1), the base frame (7) comprising Isofix connectors (8), the at least head section (3), back section (4) and sitting section (5) being rotatable relative the base frame (7),
characterized in that the base frame (7) is connected to the sitting section (5) of the child safety seat (1) through a pivot connection (9), the pivot connection (9) being arranged in a front part of the base frame (7) and the sitting section (5) of the child safety seat (1), the pivot connection (9) providing a fixed connection between the base frame (7) and the sitting section (5) under normal utilization of the child safety seat (1), but allowing at least the back section (4) and sitting section (5) to rotate sideways about an axis (R) extending through the pivot connection (9) in the event of a collision, the pivot connection (9) further comprising energy absorbing means.

### Claim 2 (depends on 1)

A child safety seat according to claim 1,
characterized in that the head section (3) and back section (4) are provided with protective wings (34).

### Claim 3 (depends on 2)

A child safety seat according to claim 2,
characterized in that the protective wings (34) over at least a part of their surface are padded with energy absorbing material.

### Claim 4 (depends on 1)

A child safety seat according to claim 1,
characterized in that the pivot connection (9) is constituted of a bolt, screw or the like, the pivot connection (9) preventing the sitting section (5) from separating from the frame (7).

### Claim 5 (depends on 4)

A child safety seat according to claim 4,
characterized in that the pivot connection (9) comprises at least one shear pin.

### Claim 6 (depends on 1)

A child safety seat according to claim 1,
characterized in that the energy absorbing means is a spring element or the like.

### Claim 7 (depends on 1)

A child safety seat according to claim 1,
characterized in that the head section (3) is connected to a vehicle seat (2) by a top tether.

### Claim 8 (depends on 1)

A child safety seat according to claim 1,
characterized in that the base frame (7) is comprised of a plate element or a plurality of beams connected to each other.
