Description
Background of the Invention
1. Field of the Invention
This invention relates to a protective apparatus for the legs or base of a child restraint seat used in a motor vehicle to reduce wear and damage to the vehicle seat coverings. The apparatus is attachable to the standard configuration child restraint seat of the type shown in the drawings to illustrate the use of the apparatus. The child restraint seat is not claimed.
2. Description of the Related Art
Child restraint seats are placed on a vehicle seat and usually secured to the vehicle frame by the seat belts of the vehicle. Over a period of time, the bottom or legs of the child restraint seat can wear or abrade the surface of the vehicle seat and cause unsightly damage. In the past, various materials have been placed under the restraint seat to reduce this wear. Vehicle owners have tried towels, diapers, blankets and other similar items to try to protect the upholstery.
U.S. Pat. No. 2,746,203 to J. A. Gibas on May 22, 1956 shows a chair shoe that is placed on a chair leg to reduce damage to a wall against which the chair might rub. The shoe keeps the chair away from the wall.
U.S. Pat. No. 3,669,490 to Doris Y. Bertolet on June 13, 1972 discloses a padded rocker channel that either lies flat for the rocker portion of the chair to rock on or the channel may be attached to the rocker portion of the chair.
U.S. Pat. No. 4,285,543 to Chester V. Clark on Aug. 25, 1981 shows a rocker attachment for a folding lawn chair to modify the chair into a rocking chair. The chair snaps into clips on the rocker attachment.
European Patent No. 0 270 035 to Frankonia Kinderaus. GMBH & Co. on June 8, 1988 describes a pad that rests on a vehicle seat surface but is not attached to the child seat. The child seat rests on the pad. The pad may be wedge-shaped so that the child seat will be angled away from the leading edge of a vehicle seat.
Summary of the Invention
The present invention is a protective apparatus for the legs or bottom of a conventional child restraint seat such as is used to seat a small child while the child is being transported in a vehicle. The protective apparatus may be made of a resilient material and attaches to the metal frame of a child restraint seat to protect the vehicles upholstery.
The apparatus is comprised of two main parts, a U-shaped base with C-shaped arms that form the U-shape. The opening of the C-shaped arms may run nearly the full length of the C-shaped arms. The small remaining portion of the arms at the extreme ends of the U-shape may not be open in order to secure the legs of the child restraint seat within the channel longitudinally. The C-shaped arms form a channel into which is inserted the legs of the child restraint seat. The channel is shown as round to receive round-shaped legs but the channel could be shaped to receive legs of other configurations. The C-shaped arms have a substantially flat bottom portion for stability. The opposing ends of the C-shaped arms are spread apart and the legs of the child restraint seat are inserted through the open portion of the C-shaped arms and then the arms snugly enclose the legs.
There are provided fastening means such as straps with buckles, quick-disconnect buckle straps or hook and mesh type fastener straps such as VELCRO, a registered trademark for a hook and mesh type fastener. The U-shaped base may be inserted into a receiving base, somewhat U-shaped, which has a bottom wall and three C-shaped side walls that accept and align with the C-shaped arms of the U-shaped base. The bottom of the U-shaped base rests on the bottom wall of the receiving base which in turn rests on the vehicular seat. The receiving base may also be used to receive a base of a child restraint seat that may have a differently configured base in the situation where the upholstery of the vehicle needs protection from a child restraint seat other then that to which the U-shaped base is attached.
The U-shaped base and the receiving base are provided with a nonskid outer surface to increase the coefficient of friction between the base and the surface against which it is placed to reduce undesired sliding. When the receiving base is used, the child restraint seat may be removed from the vehicle and used to carry the child and the receiving base left in the vehicle. Upon return to the vehicle, the child restraint seat with its U-shaped base may be placed back into the receiving base.
A protective apparatus for a child restraint seat has a first base with three sequentially connected C-shaped arms and a channel formed within the C-shaped arms to receive a portion of the legs of the child restraint seat. There is a longitudinally oriented opening in the C-shaped arms allowing access to the channel.
There is a second base having a bottom wall and three sequentially connected side walls connected to the bottom wall forming a chamber to receive the first base. The side walls have an overhanging lip to secure the first base within the chamber and there is an entrance port in the second base that allows the first base to be placed within the chamber.
The protective apparatus may have three sequentially connected C-shaped arms that form substantially a U-shape and the opening in the sequentially connected C-shaped arms may extend less than the full length of the sequentially connected C-shaped arms to secure the portion of the legs of the child restraint seat within the channel longitudinally. The first base may have a bottom support attached to the C-shaped arms and a plurality of fastening means on the C-shaped arms to secure the portion of the legs of the child restraint seat within the channel. The first base may also have an outer surface with a high coefficient of friction. The second base may have an outer surface with a high coefficient of friction.
It is therefore an object of this invention to provide a protective apparatus that has a first base that may be secured to the legs of a child restraint seat to protect the upholstery of a vehicle from unsightly wear or damage.
It is another object of this invention to provide a protective apparatus that has a second base into which the first base or a base of another type already attached to a child restraint seat may be inserted in order that the child restraint seat with the first base attached may be removed from the vehicle leaving the second base in the vehicle for convenience.
