Abstract

A support base for a child safety seat includes a shell body for supporting a child seat, a foot and a recline actuator. The shell body has a first and a second end opposite to each other, an upper surface facing upward, and an end surface extending generally vertical at the first end. The foot is disposed at a bottom of the shell body adjacent to the first end, and is movable to adjust an inclination of the support base. The recline actuator is connected with the shell body, and can engage with the foot to lock the foot in position. The recline actuator has at least an actuating portion exposed on the upper surface, the actuating portion being operable to cause an unlocking movement of the recline actuator for disengaging the recline actuator from the foot.

First claim

What is claimed is:

1 . A support base for a child safety seat, the support base comprising:
a shell body configured to support a child seat, the shell body having a first and a second end opposite to each other, an upper surface facing upward, and an end surface extending generally vertical at the first end; a foot disposed at a bottom of the shell body adjacent to the first end, the foot being movable relative to the shell body to adjust an inclination of the support base; and a recline actuator connected with the shell body, the recline actuator engaging with the foot to lock the foot in position, the recline actuator having a first actuating portion exposed on the upper surface for operation, the first actuating portion being operable to cause an unlocking movement of the recline actuator for disengaging the recline actuator from the foot.

2 . The support base according to claim 1 , wherein the recline actuator further has a second actuating portion exposed on the end surface for operation, each of the first and second actuating portions being respectively operable to cause the unlocking movement of the recline actuator for disengaging the recline actuator from the foot.

3 . The support base according to claim 1 , wherein the first actuating portion of the recline actuator is exposed on the upper surface proximate to the first end of the shell body.

4 . The support base according to claim 1 , wherein the recline actuator further includes a latching portion configured to engage with the foot for locking the foot with the shell body.

5 . The support base according to claim 4 , wherein the foot includes a plurality of locking grooves, and the latching portion selectively engages with one of the locking grooves for keeping the support base in an inclined position.

6 . The support base according to claim 2 , wherein the recline actuator, including the first and second actuating portions, is formed integrally as a single part.

7 . The support base according to claim 1 , wherein the recline actuator is pivotally connected with the shell body.

8 . The support base according to claim 1 , wherein the shell body further includes two seat mounts protruding upward and transversally spaced apart from each other, the first actuating portion being located between the two seat mounts.

9 . The support base according to claim 1 , further including a belt restraining frame pivotally connected with the shell body, the belt restraining frame being rotatable relative to the shell body between a release position where the belt restraining frame rises away from the upper surface of the shell body, and a clamping position where the belt restraining frame is adjacent to the upper surface for holding an anchoring belt.

10 . The support base according to claim 9 , wherein the belt restraining frame includes a transversal portion, two side portions, and a middle portion located between the two side portions, the two side portions and the middle portion being fixedly connected with the transversal portion and having respective ends connected pivotally with the shell body, the middle portion having an opening in which the first actuating portion of the recline actuator is at least partially received when the belt restraining frame is in the clamping position.

11 . The support base according to claim 10 , wherein the belt restraining frame is assembled with a latching member and a release actuator that are connected with each other, the latching member engaging with a corresponding structure provided on the shell body to lock the belt restraining frame in the clamping position, and the release actuator being operable to disengage the latching member from the corresponding structure on the shell body for unlocking the belt restraining frame.

12 . The support base according to claim 11 , wherein the release actuator is disposed adjacent to a junction between the middle portion and the transversal portion of the belt restraining frame.

13 . The support base according to claim 1 , wherein the shell body is further affixed with at least one cushioning part configured to deform or break under a crash load occurring during a car collision, the at least one cushioning part being closer to the second end than the first end of the shell body.

14 . The support base according to claim 13 , wherein the at least one cushioning part is made of plastics.

15 . The support base according to claim 13 , wherein the shell body further has a lateral side extending between the two first and second ends, the at least one cushioning part being adjacent to the lateral side.

16 . The support base according to claim 15 , wherein the at least one cushioning part is exposed outward on the lateral side of the shell body.

17 . The support base according to claim 13 , wherein the shell body further has two opposite lateral sides extending between the two first and second ends, the at least one cushioning part including two cushioning parts respectively adjacent to the two lateral sides of the shell body.

18 . The support base according to claim 13 , wherein the shell body further has a first and a second region respectively adjacent to the first and second end, the first region projecting upward higher than the second region, and the at least one cushioning part being provided in the second region of the shell body.

19 . The support base according to claim 13 , wherein the at least one cushioning part includes one or more inner cavity.

20 . The support base according to claim 1 , wherein the first end of the shell body is positioned against a seatback of the vehicle seat when the support base is installed on a vehicle seat.

21 . The support base according to claim 1 , wherein the foot is pivotally connected with the shell body.

22 . A support base for a child safety seat, the support base comprising:
a shell body configured to support a child seat, the shell body having a first and a second end opposite to each other, and two opposite lateral sides extending from the first end to the second end, the first end of the shell body being positioned against a seatback of a vehicle seat when the support base is installed on the vehicle seat; and a cushioning part affixed with the shell body and configured to deform or break under a crash load occurring during a car collision, the cushioning part being closer to the second end than the first end of the shell body.

23 . The support base according to claim 22 , wherein the cushioning part is disposed adjacent to at least one of the two lateral sides of the shell body.

24 . The support base according to claim 22 , wherein the cushioning part includes one or more inner cavity.

25 . The support base according to claim 22 , wherein the cushioning part is exposed outward on at least one of the two lateral sides of the shell body.

26 . The support base according to claim 22 , wherein the cushioning part is made of plastics.
