Abstract

A safety system comprising: a passenger seat (10) having fixed anchors (14) adapted to secure and retain a child seat (40;70); the child seat having clamps (50,52) for lockingly engaging a respective one of the anchors; and a switch (80,80'"'"') mounted in proximity to at least one of the anchors (14), having an active state and an inactive state, wherein when the clamp lockingly engages a corresponding anchor the state of the switch is changed to provide an indication that a child seat has been installed.

Claims

1. A safety system comprising:

a passenger seat (10) having fixed anchors (14) adapted to secure and retain a child seat (40;

70);

the child seat having clamp means (50,52) for lockingly engaging the anchors;

switch means (80,80'"'"') mounted in proximity to at least one of the anchors (14), having an active state and an inactive state, wherein with the clamp means lockingly engaging a corresponding anchor the state of the switch means is changed to provide an indication that a child seat has been installed.

2. The system as defined in claim 1 wherein the switch means includes first means capable of discriminating between different types of child seats including a front facing child seat and a rear facing child seat.

3. The system as defined in claim 1 including an air bag and inflator, wherein the operation of the inflator is modified in accordance with the installation of the child seat.

4. A safety system comprising:

a passenger seat (10) having at least one first connector part (14) lockingly engageable with a second connector part on a child seat;

switch means (80,80'"'"') mounted in proximity to at least one first connector part (14), having an active state and an inactive state, wherein with the second connector part lockingly engaging a corresponding first connector part the state of the switch means is changed to provide an indication that a child seat has been installed.

5. The system as defined in claim 4 wherein the switch means includes first means capable of discriminating between different types of child seats including a front facing child seat and a rear facing child seat.

6. The system as defined in claim 4 including an air bag and inflator, wherein the operation of the inflator is modified in accordance with the installation of the child seat.

7. The system as defined in claim 4 wherein the first connector part includes one of an anchor and a clamp and the second connector part includes the other of the clamp and the anchor.

8. The system as defined in claim 4 wherein the seat includes a plurality of first connector parts engageable with a like plurality of second connector parts on the child seat.

9. A safety system comprising:

a child seat having at least one interlocking first connector part (50,52) for lockingly engaging a mating corresponding interlocking second connector part installed within a vehicle seat, the child seat including a portion whereby upon mating of the child seat to the vehicle seat the portion engages with switch means (80,80'"'"') mounted in proximity to the mating second connector part (14), the switch means having an active state and an inactive state, wherein with the connector parts lockingly engaged the state of the switch means is changed to provide an indication that a child seat has been installed.

10. A safety system comprising:

a passenger seat (10) having at least first connector (14) adapted to secure and retain a child seat (40;

70);

the child seat having at least a second connector (50,52) for lockingly engaging with corresponding first connectors;

switch means (80,80'"'"') mounted in proximity to at least one of the first connectors (14), having an active state and an inactive state, wherein with the second connector lockingly engaging a corresponding first connector the state of the switch means is changed to provide an indication that a child seat has been installed.
