Abstract

The invention concerns a child car seat, comprising a base (12, 201) and a seat (11, 91) pivoting in relation to said base (12, 201) in such as way as to assume at least two positions:

• • an utilisation position (facing the road), in which a locking element (14, 203) affixed to the upper part of the backrest of said seat (11) and a locking element (21, 202) affixed to said base (12, 201) are locked together
  • at least one installation position (facing a door), in which said locking elements (14, 203, 21, 202) are unlocked.

According to the invention, one of said first locking elements comprises at least one mobile hook (203, 21) that can move from an unlocked position to a locked position in which it cooperates with a fixed hooking element (202, 14) of said second locking element, and in that it comprises at least one latch (206, 207) that can assume two positions:

• • a rest position in which said latch or latches (206, 207) hold said hook (203) in its unlocked position
  • a release position in which said hook (203) moves to its locked position.

Claims

1. A child car seat, comprising a base (12, 201) and a seat (11, 91) pivoting in relation to said base (12, 201) in such a way as to assume at least two positions:

an utilisation position, in which said seat (11, 91) is facing the road, and in which the locking means comprising a locking element affixed to the upper part of the backrest (111) of said seat (11, 91) and a locking element affixed to said base (12, 201) are locked together;

at least one installation position, in which said seat (11, 91) is turned towards a door of a vehicle, and in which said locking elements are unlatched,

characterised in that the first of said locking elements has at least one mobile hook (203) that can move from the unlocked position to the locked position in which it cooperates with a fixed hooking element (202) of the second of said locking elements, and in that it comprises at least one latch (206, 207) that may assume two positions;

an at rest position in which said latch or latches (206, 207) hold said hook (203) in its unlocked position;

a release position in which said hook (203) moves to its locked position.

2. A child car seat according to claim 1, characterised in that at least one of said latches (206, 207) moves from said freed position under the action of said fixed element (202) when said seat moves from one of said installation positions to said utilisation position.

3. A child car seat according to either of claims 1 or 2, characterised in that at least one of said latches (206, 207) is configured so as to move into said freed position in two ways:

when said backrest (111) is pivoted in a direction significantly parallel to said backrest (111);

when said backrest (111) is pivoted in a direction significantly perpendicular to said backrest (111).

4. A child car seat according to any of claims 1 to 3, characterised in that said hook (203) is associated with the first means of return (209) that tends to bring it into its locked position.

5. A seat according to any of claims 1 to 4, characterised in that the latch or latches (206, 207) are associated with a second means of return (210, 211) that tends to bring it or them into said rest position.

6. A child car seat according to any of claims 1 to 5, characterised in that it has a locking means permitting the movement of said hook (203) into said unlocked position.

7. A child car seat according to claim 6, characterised in that said means of unlocking are controlled in a remote manner by at least one control cable (212).

8. A child car seat according to any of claims 1 to 7, characterised in that it has a visual means of checking (215) the moving of said hook (203) into said locked position.

9. A child car seat according to any of claims 1 to 8, characterised in that it has two latches (206, 207) and in that said hook (203) moves into said locked position when said two latches (206, 207) are in said freed position.

10. A child car seat according to any of claims 1 to 9, characterised by said latches (206, 207) being symmetrically mounted in relation to said hook (203).

11. A child car seat according to any of claims 1 to 10, characterised in that said seat comprises an indexing means (911, 912, 92), controlling the correct placing of said seat (11, 91) in said utilisation position.

12. A child car seat according to claim 11, characterised in that said indexing means comprises at least one mobile element (92) that can assume at least two positions, one position in which it authorises a rotation of said seat (11) to the right, and one position in which it authorises a rotation of said seat to the left.
