Apparatus for use in a child safety seat
An apparatus for a child safety seat is disclosed. The apparatus comprises a releasable connector configured to engage with an anchoring point provided in a vehicle to secure the child safety seat to the vehicle, wherein the releasable connector is movable relative to the child safety seat in a first direction; the apparatus further comprises a braking element coupled to the releasable connector and configured to decelerate a movement of the releasable connector in the first direction if an accelerating force acting on the releasable connector in the first direction exceeds a predetermined threshold.
1. An apparatus for a child safety seat, the apparatus comprising:
a releasable connector configured to engage with an anchoring point provided in a vehicle to secure the child safety seat to the vehicle, wherein the releasable connector is movable relative to the child safety seat in a first direction; and
a braking element coupled to the releasable connector and configured to decelerate a movement of the releasable connector in the first direction in response to an accelerating force, acting on the releasable connector in the first direction, exceeding a predetermined threshold,
wherein the braking element is pivotally coupled to the releasable connector and is configured to rotate about a rotation axis of the braking element which is spaced apart from the center of gravity of the braking element such that a rotary force acts on the braking element in response to the releasable connector accelerating.
2. The apparatus of claim 1 , wherein the braking element is additionally connected to the releasable connector by an elastic element such that an elastic force caused by the elastic element acts against the rotary force caused by an acceleration of the releasable connector in the first direction.
3. The apparatus of claim 2 , wherein the elastic element is a spring.
4. The apparatus of claim 1 , wherein the releasable connector comprises an ISOFIX connector of a child safety seat.
5. The apparatus of claim 1 , wherein the braking element is configured to decelerate the movement of the releasable connector by providing a friction force caused by friction between the braking element and a surface of the child safety seat.
6. The apparatus of claim 1 , further comprising a plate element configured to be mounted on a surface of the child safety seat such that the plate element comes into contact with the braking element in response to the accelerating force, acting on the releasable connector in the first direction, exceeding the predetermined threshold.
7. The apparatus of claim 6 , wherein at least a part of the surface of the braking element is serrated.
8. The apparatus of claim 6 , wherein at least a part of the surface of the plate element is serrated.
9. The apparatus of claim 6 , wherein the plate element comprises plastic and the braking element comprises metal.
10. The apparatus of claim 6 , wherein materials of the braking element and the plate element are selected such that a coefficient of friction of the material of the braking element and the plate element is a predefined amount for the braking element and the plate element to become wedged together in response to the accelerating force, acting on the releasable connector in the first direction, exceeding a predetermined threshold.
11. A child safety seat comprising an apparatus, the apparatus comprising:
a releasable connector configured to engage with an anchoring point provided in a vehicle to secure the child safety seat to the vehicle, wherein the releasable connector is movable relative to the child safety seat in a first direction; and
a braking element coupled to the releasable connector and configured to decelerate a movement of the releasable connector in the first direction in response to an accelerating force, acting on the releasable connector in the first direction, exceeding a predetermined threshold,
wherein the braking element is pivotally coupled to the releasable connector and is configured to rotate about a rotation axis of the braking element which is spaced apart from the center of gravity of the braking element such that a rotary force acts on the braking element in response to the releasable connector accelerating.
12. The child safety seat of claim 11 , wherein the child safety seat is configured for a rear-facing installation in the vehicle.
13. The child safety seat of claim 11 , wherein the braking element is additionally connected to the releasable connector by an elastic element such that an elastic force caused by the elastic element acts against the rotary force caused by an acceleration of the releasable connector in the first direction.
14. The child safety seat of claim 13 , wherein the elastic element is a spring.
