  • Publication number: 20250083578
    Abstract: A convertible child restraint includes a lower base to contact a vehicle seat, a seat shell to support a child, and a mid base between the lower base and the seat shell to facilitate recline and rotational adjustment of the seat shell relative to the lower base. The child restraint may be used as a rear-facing car seat, a forward-facing car seat, and a belt positioning booster seat. For the rear-facing car seat configuration, a belt is installed along a rear-facing belt path that passes through the child restraint. The portion of the belt in the child restraint is accessed via a belt access panel when the seat shell is at a rear-facing position. Additionally, the child restraint includes a rotation lockout that allows the seat shell to be rotated from a rear-facing position to a side-facing position, but not a forward-facing position when using the rear-facing configuration.

  • Publication number: 20240416807
    Abstract: In one example, a child car seat for a vehicle has a main body with seatback, a seating surface that extends forward from the seatback, and a recline foot. The recline foot has a front end that defines an engagement region that engages a vehicle seat, and a rear end disposed behind the front end. The rear end is coupled to the main body such that the recline foot pivots relative to main body about a pivot axis to transition the main body between at least one reclined position and at least one inclined position. The rear end has a rigid portion, and the car seat has a deformable body affixed to the rigid portion. The deformable body engages the vehicle seat and deforms under a lower force than the rigid portion.

  • Patent number: 11938848
    Abstract: A child restraint system is provided and configured to be installed on a vehicle seat to support a child. The child restraint system includes a main body, a reclining foot and an adjusting foot. The main body includes a seat portion and a backrest portion. The reclining foot is pivotably coupled to the main body. The adjusting foot is pivotably coupled to the main body or the reclining foot. The adjusting foot is pivotable between a forward position and a rearward position. No matter when the child restraint system is in a rearward-facing direction or a forward-facing direction, the child restraint system can be supported stably on the vehicle seat, and a recline position of the child restraint system can be adjusted in a wide adjustment range by pivoting of the reclining foot. Therefore, the child restraint system is convenient to use.
