Abstract

A seat anchoring element for child safety seats or baby carriers has an anchoring element which can be secured to fixation elements on the vehicle seat, or to the vehicle body, by connectors at the ends of a separate strap system. The seat anchoring element comprises at least one front and rear securing element on the upper face for fixing the child safety seat or the baby carrier thereto, and least one tensioning device for those parts at the ends of which the connectors are located. The straps of the strap system can be wound onto a ratchet spool of the tensioning device and can be unwound after a locking mechanism of the ratchet is unlocked. A lever mounted pivotably with the seat anchoring element is coupled with the ratchet, wherein the bearing axis of the lever runs transversely to the longitudinal axis of the seat anchoring element.

Claims

1. Seat anchoring element (1) for child safety seats or baby carriers on a vehicle seat, which is fastenable to fixing elements (7, 8) in or at the vehicle seat or the vehicle bodywork behind the vehicle seat by means of connectors (4, 5) at the ends of an own belt system consisting of two laterally and/or rearwardly accessible belts (2, 3) or at the ends of a transverse belt (6) or at the ends of rearwardly protruding rods (32) mounted to be displaceable laterally with respect to the centre longitudinal axis, which seat anchoring element (1) has at the upper side at least one front fastening element (9) and at least one rear fastening element (10) for fixing the child safety seat or the baby carrier thereto and at least one tensioning device for the parts, at the ends of which the connectors (4, 5) are disposed, wherein the belts (2, 3) of the belt system or the belts (2) connected with the rods (32) or a common tensioning belt (11) connected with the individual belts (2, 3) can be wound up on a ratchet drum (12) at the tensioning device and after unlocking of blocking means of the ratchet (13) can be at least partly unwound, which ratchet drum (12) is rotatably mounted in the seat anchoring element (1), and a lever (14), which is pivotably mounted in the seat anchoring element (1) and which is pivotable into a recess (15) in the seat anchoring element (1) from an upright ratchet actuating setting for tensioning the belts (2, 3) or the tensioning belt (11) to a recessed rest setting, is coupled with the ratchet (13), wherein at least the axis of the pivot of the lever extends transversely to the longitudinal axis of the seat anchoring element (1).

2. Seat anchoring element according to claim 1, wherein the lever (14) is the same width as or wider than the width of the ratchet drum (12) and is pivotable into a contour-matched U-shaped recess (15) to be locked.

3. Seat anchoring element according to claim 1, wherein the lap belt of a vehicle belt or the lap belt section of a three-point vehicle belt by itself or together with the shoulder belt section or a separate transverse belt (6) is insertable in transverse direction to extend over the recess, the free belt ends of which are each connectible by way of a lock tongue with a lock at the vehicle'"'"'s own seat or therewith by way of connecting elements.

4. Seat anchoring element according to claim 2, wherein the transverse belt (6) extends under the lever (14), only when this is in the rest setting, transversely through the recess (15).

5. Seat anchoring element according to claim 1, wherein the lever (14) has a handle (16) at the upper side.

6. Seat anchoring element according to claim 1, wherein the lever (14) is held in the recessed position in the recess (15) by means of a locking device.

7. Seat anchoring element according to claim 6, wherein the locking device consists of a latch, a detent lug or a locking pin, which is mounted at the lever (14) or a wall of the recess and with which a corresponding counter-element at the other part co-operates and that at least one actuating element (17), on actuation of which the locking device releases the lever (14) for pivotation, for an unlocking mechanism is provided at one of the parts.

8. Seat anchoring element according to claim 5, wherein two laterally projecting actuating elements (17) are mounted in the handle (16) to be displaceable against the force of a spring arrangement and when operated simultaneously release the locking device.

9. Seat anchoring element according to claim 2, wherein the lever (14) has two lateral mounting limbs (18) which engage over the ratchet drum (12) and which are pivotably mounted on the axle of the ratchet drum (12).

10. Seat anchoring element according to claim 1, wherein the seat anchoring element (1) has at the rear side an elevated wall (19) supported at the backrest of the vehicle seat.

11. Seat anchoring element according to claim 9, wherein the wall (19) extends at an inclination from below to above in the depth of the seat cushion element and that the U-shaped recess (15) for reception of the lever (14) is formed in this element.

12. Seat anchoring element according to claim 5, wherein a mounting recess (20) for receiving the handle (16) of the lever (14) is provided in the upper section of the wall (19).

13. Seat anchoring element according to claim 1, wherein the lateral belts (2, 3) are so guided through passages (21, 22) and deflections (23) formed in the rear wall (19) of the seat anchoring element (1) that on connecting the connectors (4, 5) with the fixing elements (7, 8) and on tensioning the belts (2, 3) or the common tensioning belt (11) the seat anchoring element (1) rests under tension on the vehicle seat with simultaneous pressure against the backrest of the vehicle seat.

14. Seat anchoring element according to claim 1, wherein the two lateral belts (2, 3) or the two belts (2, 3) at the rods (32) are fastened in common to a tensioning belt (11) or a tensioning belt (11) is fastened to a bridge part connecting the two rods (32) and that the tensioning belt (11) is so guided through a central deflection (23, 24) that the winding end can be wound up on and unwound from the ratchet drum (12).

15. Seat anchoring element according to claim 1, wherein lateral passages (21, 22) through which the transverse belt (6) or the lap belt section of the vehicle'"'"'s own safety belt is led are provided parallel to the centre wall section of the wall (19) of the seat anchoring element (1) to which the lever is fastened and mounted.

16. Seat anchoring element according to claim 1, wherein the seat anchoring element (1) consists of plastics material.
