Abstract

The invention concerns a child car seat, comprising a base (12, 31, 604, 72) and a seat (11) pivoting in relation to said base (12, 31, 604, 72) so as to assume at least two positions:

• • an utilisation position (facing the road), in which a locking element (14, 34, 601, 73) affixed to the upper part of backrest (111, 33, 602, 74) of said seat (11) and a locking element (21, 32, 603, 71) affixed to said base (12, 31, 604, 72) are locked
  • at least one installation position (facing the car door), in which said locking elements are unlocked.

According to the invention, the first of said locking elements (32, 601, 71) comprising at least two guiding surfaces (325, 6011, 715, 716, 321, 322, 323, 324, 6012, 6013, 711, 712) configured so as to bring said locking elements into the locked position as soon as said seat (11) is in said utilisation position.

Claims

1. A child car seat, comprising a base (12, 31, 604, 72) and a seat (11) pivoting in relation to said base (12, 31, 604, 72) in such a way as to assume at least two positions:

an utilisation position, in which said seat (11) is facing the road, and in which the locking means comprising a locking element (14, 34, 601, 73) affixed to the upper part of backrest (111, 33, 602, 74) of said seat (11) and a locking element (21, 32, 603, 71) affixed to said base (12, 31, 604, 72) are locked together,

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

characterised in that the first (32, 601, 71) of said locking elements has at least two guiding surfaces including;

a frontal guiding surface (325, 6011, 715, 716) cooperating with at least one mobile part (342, 343, 603, 73) of the second of said locking elements, when said seat (11) moves from said utilisation position via movement of said backrest (111, 33, 602, 74) in a direction significantly perpendicular to said backrest (111, 33, 602, 74),

a lateral guiding surface (321, 322, 323, 324, 6012, 6013, 711, 712) cooperating with at least one of said mobile parts (342, 343, 603, 73), when said seat (11) moves to said utilisation position via movement of said backrest (111, 33, 602, 74) in a significantly parallel direction to said backrest (111, 33, 602, 74),

said guiding surfaces being configured to bring said locking elements into the locked position as soon as said seat (11) is in said utilisation position.

2. A child car seat according to claim 1, characterised in that said seat (11) may assume at least two installation positions, by a rotation to the left or a rotation to the right respectively in relation to said base (12, 31, 604, 72), and in that said first locking element comprises two lateral guiding surfaces (321, 322, 323, 324, 6012, 6013, 711, 712) cooperating respectively with at least one of said mobile parts (342, 343, 603, 73) when said seat (11) is pivoted from one or other of said installation positions.

3. A child car seat according to either of claims 1 or 2, and characterised in that said mobile parts (342, 343, 603, 73) are associated with means of return (606, 75) that tend to bring them into said locked position.

4. A child car seat according to any of claims 1 to 3 characterised in that it has an unlocking means allowing said mobile part(s) (342, 343, 603, 73) to move to said unlatched position.

5. A child car seat according to claim 4, characterised in that unlocking means are remotely operated by at least one control cable (37, 610, 76).

6. A child car seat according to any of claims 1 to 5, characterised in that it has a visual means of checking the locking or unlocking (620) of said locking means.

7. A child car seat according any of claims 1 to 6, characterised in that said lateral guiding surface(s) (321, 322, 323, 324, 711, 712) form at least one slide (32, 71) leading to at least one locking housing (35, 713, 714).

8. A child car seat according to claim 7,

characterised in that said second locking element forms a hook (34) that has at least two mobile teeth (342, 343) cooperating with said locking housing (35) in said locked position.

9. A child car seat according to claim 7, characterised in that said mobile part is a hook (73) pivoting around a perpendicular shaft of said backrest (111, 33, 602, 74), with at least one extremity (733) cooperating with at least one of said housings (713, 714) in the locked position.

10. A child car seat according to any of claims 1 to 6, characterised in that said mobile part is a hook (603) see-sawing around a horizontal axis (605), and cooperating with a portion of said first locking element (601) and having a significantly U-shaped form in said locked position.

11. A child car seat according to any of claims 1 to 10, characterised in that said seat has an indexing means (132, 1311, 1312), controlling the correct placement of said seat (11) in said utilisation position.

12. A child car seat according to claim 11, characterised in that said indexing means have at least one mobile element (132) that may assume at least two positions, one position in which it allows turning of said seat (11) to the right, one position in which it allows turning of said seat (11) to the left.
