Abstract

A child restraint includes a juvenile seat and a base for supporting the juvenile seat. The base is adapted to be anchored to lie in a stationary position on a passenger seat of a vehicle to support the juvenile seat in the vehicle.

Claims

1. A child restraint comprising

a juvenile holder including a seat-support base and a juvenile seat configured to the mounted on the seat-support base, the seat-support base including a foundation adapted to set on a passenger seat in a vehicle, a pivotable belt clamp mounted for movement about a forward pivot axis associated with a forward bottom end of the foundation from a closed belt-trapping position in a direction away from a rearward top end of the foundation to an opened belt-receiving position to expose a seat belt-receiver cavity formed in the foundation, a top-end clamp anchor coupled to the pivotable belt clamp to pivot therewith about the forward pivot axis and configured to lock the pivotable belt clamp to the foundation to retain the pivotable belt clamp in the closed belt-trapping position to trap portions of shoulder and lap straps of a vehicle seat belt located in the seat belt-receiver cavity formed in the foundation to tension the shoulder and lap straps included in the vehicle seat belt so that the seat-support base is anchored in a stationary position on the passenger seat, and a seat mount coupled to the pivotable belt clamp to move therewith and oriented to engage and support the juvenile seat in a stationary juvenile-seating position relative to the seat-support base upon pivotable movement of the pivotable belt clamp to the closed belt-trapping position.

2. The child restraint of claim 1, wherein the seat mount is arranged to slide back and forth on the top of the pivotable belt clamp from a retracted anchor-hiding position in which the top-end clamp anchor is hidden from view in a space provided between the pivotable belt clamp and the seat mount to an extended anchor-access position that reveals and exposes the top-end clamp anchor so that it can be accessed and operated by a caregiver during removal of the seat-support base from an anchored stationary position on a passenger seat of a vehicle.

3. The child restraint of claim 2, wherein the seat mount is configured to slide along a curved path relative to the pivotable belt clamp between the retracted anchor-hiding position and the extended anchor-access position.

4. The child restraint of claim 2, wherein the top-end clamp anchor comprises a first pivot blocker mounted on a free upper end of the pivotable belt clamp for lateral movement relative to the pivotable belt clamp to engage and disengage a companion blocker receiver formed in the rearward top end of the foundation.

5. The child restraint of claim 4, wherein the first pivot blocker includes a first retainer pin mounted to move laterally back and forth in a pin-receiver passageway formed in the free upper end of the pivotable belt clamp and arranged to lie in side-by-side communication with the companion blocker receiver formed in the rearward top end of the foundation when the pivotable belt clamp occupies the closed belt-trapping position and a first pin-biasing spring arranged to move the first retainer pin in the pin-receiver passageway of the pivotable belt clamp to extend into the companion blocker receiver of the foundation to retain the pivotable belt clamp in the closed belt-trapping position on the foundation.
