Abstract
Abstract A child car seat having an improved restraint system in which the restraint system may be easily connected and disconnected, automatically placed about the child in the proper position, and automatically adjusted to properly secure the child within the seat. The restraint system includes a pivotal barrier assembly, a harness assembly, and an adjusting assembly, each of which is interconnected. As a portion of the barrier assembly is pivoted into a position in front of the child, the harness assembly is automatically placed upon the child in the proper position. Moreover, the harness assembly is automatically adjusted about the child by the adjusting assembly. When the restraint system is in the locked position by locking of the barrier assembly, further loosening of the harness assembly is substantially prohibited by the adjusting assembly. However, the adjusting assembly is able to act upon the harness assembly to automatically remove any slack therefrom which may exist either before or after locking of the restraint system.
