Abstract

A support base for a child safety seat includes a shell, a belt clamp, a latching mechanism and a belt retaining structure. The shell is adapted to receive a child seat thereon, and has a panel at an end thereof. The belt clamp is pivotally connected with the shell and is disposed adjacent to the panel, the panel rising above the belt clamp, the belt clamp being operable to clamp a lap belt portion of a vehicle safety belt adjacent to a surface of the shell. The latching mechanism is operable to lock the belt clamp in a clamping state. The belt retaining structure is provided on the panel, and is configured to hold a shoulder belt portion of a vehicle safety belt adjacent to the panel.

Claims

1. A support base for a child safety seat, comprising:

a shell adapted to receive a child seat thereon, an end of the shell having a panel, and the shell further including a belt anchoring region adjacent to the panel, the belt anchoring region including a first and a second surface contiguous to each other, the second surface being supported by the panel and rising above the first surface;

a belt clamp pivotally connected with the shell, the belt clamp being operable to clamp a first and a second belt portion respectively adjacent to the first and second surface; and

a latching mechanism operable to lock the belt clamp in a clamping state.

2. The support base according to claim 1, wherein an angle defined between the first and second surfaces is equal to or greater than 90 degrees.

3. The support base according to claim 1, wherein the belt clamp includes a first and a second clamp portion, the second clamp portion extending at an angle from the first clamp portion, the first clamp portion being adapted to clamp a first belt portion adjacent to the first surface, and the second clamp portion being adapted to clamp a second belt portion adjacent to the second surface.

4. The support base according to claim 3, wherein the belt clamp including the first and second clamp portions is formed as a unitary part.

5. The support base according to claim 3, wherein the second clamp portion is pivotally connected with the panel of the shell.

6. The support base according to claim 3, wherein the belt clamp is rotatable relative to the shell between the clamping state where the first and second clamp portion are respectively positioned adjacent to the first and second surface, and a release state where the first and second clamp portion are respectively displaced generally away from the first and second surface, the first and second clamp portions being movable in unison as the belt clamp rotates between the clamping state and the release state.

7. The support base according to claim 3, wherein the latching mechanism includes a latch connected with the belt clamp, the latch being movable to engage and disengage the shell, the latch being engaged with the shell for locking the belt clamp in the clamping state, and the latch being disengaged from the shell for unlocking the belt clamp.

8. The support base according to claim 7, wherein the latch is operable to project at an underside of the first clamp portion.

9. The support base according to claim 7, wherein the latching mechanism further includes a spring respectively connected with the belt clamp and the latch, the spring biasing the latch toward a locking state for locking engagement with the shell.

10. The support base according to claim 7, wherein the latching mechanism further includes a release actuator disposed adjacent to the latch on the belt clamp, the release actuator being operable to urge the latch to disengage from the shell for unlocking the belt clamp.

11. The support base according to claim 1, further including a second spring connected with the belt clamp, the second spring being operable to bias the belt clamp toward a release state when the latching mechanism unlocks the belt clamp.

12. A support base for a child safety seat, comprising:

a shell adapted to receive a child seat thereon, an end of the shell having a panel, and the shell further including a belt anchoring region adjacent to the panel, the belt anchoring region including a first and a second surface contiguous to each other, the second surface being supported by the panel and rising above the first surface;

a belt clamp pivotally connected with the shell and having a belt retaining structure, the belt clamp being operable to clamp a lap belt portion of a vehicle safety belt adjacent to the first surface, and the belt retaining structure being adapted to hold a shoulder belt portion of a vehicle safety belt adjacent to the second surface when the lap belt portion is clamped adjacent to the first surface; and

a latching mechanism operable to lock the belt clamp in a clamping state.

13. The support base according to claim 12, wherein an angle defined between the first and second surfaces is equal to or greater than 90 degrees.

14. The support base according to claim 12, wherein the belt clamp including the belt retaining structure is formed as a unitary part.

15. The support base according to claim 12, wherein the belt clamp includes a first and a second clamp portion, the second clamp portion extending at an angle from the first clamp portion and forming the belt retaining structure, the first clamp portion being adapted to clamp a lap belt portion of a vehicle safety belt adjacent to the first surface, and the second clamp portion being adapted to clamp a shoulder belt portion of a vehicle safety belt adjacent to the second surface.

16. The support base according to claim 12, wherein the latching mechanism includes a latch connected with the belt clamp, the latch being movable to engage and disengage the shell, the latch being engaged with the shell for locking the belt clamp in the clamping state, and the latch being disengaged from the shell for unlocking the belt clamp.

17. The support base according to claim 16, wherein the latching mechanism further includes a spring respectively connected with the belt clamp and the latch, and a release actuator disposed adjacent to the latch on the belt clamp, the spring biasing the latch toward a locking state for locking engagement with the shell, and the release actuator being operable to urge the latch to disengage from the shell for unlocking the belt clamp.

18. The support base according to claim 12, further including a second spring connected with the belt clamp, the second spring being operable to bias the belt clamp toward a release state when the latching mechanism unlocks the belt clamp.
