Abstract

A child restraint system that is adapted to be mounted within a vehicle is provided. The child restraint system includes a child seat configured to receive a child occupant. The child seat has a frame, at least first and second docking stations, and a child seat monitoring device. The first and second docking stations are disposed at first and second locations on the frame. Both of the first and second docking stations are configured to receive and hold the child seat monitoring device therein.

Claims

1. A child restraint system adapted to be mounted within a vehicle, the child restraint system comprising:

a child seat configured to receive a child occupant, the child seat having a frame, at least first and second docking stations, and a child seat monitoring device, the first and second docking stations being disposed at first and second locations on the frame, both of the first and second docking stations configured to receive and hold the child seat monitoring device therein.

2. The child restraint system of claim 1, wherein the first docking station comprises an outer peripheral wall and a rear wall, the outer peripheral wall defining an interior region for receiving the child seat monitoring device, the outer peripheral wall extending from a first end to a second end, the rear wall enclosing the second end of the outer peripheral wall.

3. The child restraint system of claim 2, wherein the child seat monitoring device comprises a front surface, a rear surface, a peripheral surface coupled between the front surface and the rear surface, and a plurality of light emitting indicators disposed on the front surface.

4. The child restraint system of claim 3, wherein the peripheral surface of the child seat monitoring device has at least first and second latching members extending therefrom.

5. The child restraint system of claim 4, wherein the outer peripheral wall of the first docking station defines first and second grooves extending from the second end toward the first end, the outer peripheral wall having first and second wall portions disposed in the first and second grooves, respectively, proximate the first end for holding the first and second latching members, respectively.

6. The child restraint system of claim 5, wherein the first latching member has a first operational position where the first latching member fixedly engages the first wall portion and a second operational position wherein the first latching member disengages the first wall portion.

7. The child restraint system of claim 3, wherein the peripheral surface of the child seat monitoring device has first and second tab members extending therefrom.

8. The child restraint system of claim 7, wherein the outer peripheral wall of the first docking station has first and second grooves extending from the second end toward the first end, the outer peripheral wall having first and second wall portions disposed in the first and second grooves, respectively, proximate the first end for holding the first and second tab members, respectively.

9. The child restraint system of claim 3, wherein the peripheral surface of the child seat monitoring device has first and second guiding members, respectively, extending therefrom.

10. The child restraint system of claim 9, wherein the outer peripheral wall of the first docking station has first and second grooves extending from the first end inwardly into the outer peripheral wall, the first and second grooves configured to receive the first and second guiding members, respectively, therein.

11. The child restraint system of claim 3, wherein the outer peripheral wall has a plurality of centering tabs into the interior region for centering the child seat monitoring device in the interior region.

12. The child restraint system of claim 2, wherein the rear wall of the first docking station has at least one cantilever beam portion configured to urge the child seat monitoring device disposed in the region toward the first end of the outer peripheral wall.

13. The child restraint system of claim 2, wherein the outer peripheral wall has generally rectangular ring shape.

14. The child restraint system of claim 1, wherein both of the first and second docking stations are further configured to release the child seat monitoring device therefrom.

15. The child restraint system of claim 1, wherein the child seat monitoring device is configured provide visual feedback messages indicating whether the child seat has been installed in the vehicle in accordance with at least one predetermined installation parameter.

16. The child restraint system of claim 1, wherein the child seat monitoring device comprises a processing unit configured to be electrically coupled to at least a first sensor generating a first signal indicative of a child seat parameter, the processing unit further configured to receive the first signal and to determine whether the child seat is installed in the vehicle in accordance with a predetermined installation parameter based on the first signal.

17. A child seat monitoring device, comprising:

a removable housing configured to be removably secured to at least one docking station disposed on a child seat; and

a processing unit disposed in the housing, the processing unit configured to be electrically coupled to at least a first sensor when the housing is disposed in the docking station on the child seat, the first sensor generating a first signal indicative of a child seat parameter, the processing unit further configured to receive the first signal and to determine whether the child seat is installed in a vehicle in accordance with a predetermined installation parameter based on the first signal.

18. The child seat monitoring device of claim 17, wherein the housing has a front surface, a rear surface, a peripheral surface disposed between the front surface and the rear surface, first and second latching members extending from the peripheral surface, first and second tab portions extending from the peripheral surface, and at least one light emitting device operably coupled to the processing unit, the light emitting device being disposed on the front surface, the first and second latching members having a first operational position for coupling the housing to the docking station disposed on the child seat and a second operational position for decoupling the housing from the docking station.

19. The child seat monitoring device of claim 18, wherein the housing further comprises first and second guiding members, respectively, extending from the peripheral surface for guiding the housing into the docking station.

20. The child seat monitoring device of claim 18, wherein the processing unit is further configured to generate a second signal to induce the light emitting device to emit light when the first signal indicates the child seat was not installed in the vehicle in accordance with the predetermined installation parameter.
