## Title
Removable car seat cover

## Abstract

A removable car seat cover has openings adapted to allow the crotch strap and shoulder straps to extend through the cover while the straps remain affixed to the car seat. The removable cover comprises a periphery that secures the cover to the edges of a car seat. Various configurations of openings for shoulder straps to extend through include: two vertical openings, a “U”-shaped opening, multiple horizontal openings connected by a vertical slit and openings for shoulder belts used with booster seats. Fasteners and panels can be added to each configuration to provide further protection to the underlying factor car seat cover. A matching canopy cover has extended panels to provide additional protection from rain or the sun.

## Background
FIELD OF THE INVENTION
The invention relates to automotive safety seats for children in general, and in particular to a detachable supplemental cover for a child's car seat.
BACKGROUND OF THE INVENTION
Children sit in a car seat with a restraint system while traveling by automobile. Some car seats can be removed from the car for use as a carrier or for placement on a stroller. Child car seats are generally made with a molded plastic shell covered with a padded seat cover. Harness straps and hardware for securing the child extend through openings in the padded cover and are anchored to the plastic shell. The safety harness comes in either a 3-point, 5-point and 6-point configuration. The 3-point harness has a strap over each shoulder which come together and attach at the crotch. In the five-point harness, a lap belt integrates with or attaches to the shoulder straps, which then attach at the crotch. A six-point harness is configured much like a 5-point harness, but has two connection points at the crotch. Car seat covers generally have multiple openings for threading straps through the cover, allowing adjustments for different sized children. Usually, the upper anchor points for the shoulder straps allow for adjustments to the strap lengths.
Car seats come in multiple sizes and configurations. Generally, car seats are rear-facing for infants and forward facing for toddlers. Convertible seats work both ways, changing from rear facing to forward facing as the child grows. Many infant car seats have a fabric canopy attached to the car seat. The canopy extends over a portion of the car seat to shade children from the sun. Booster seats are similar to toddler seats, but integrate with a car's seatbelt rather than using an integrated harness. Clips or openings position a shoulder belt in the proper location to restrain the child.
Children soil their car seat covers easily. As a result, manufacturers of car seats generally make a removable padded cover that can be laundered. Caregivers, however, find removing car seat covers for laundering difficult. To remove a seat cover, the seat must be removed from the car, the straps must be unthreaded from the openings in the seat cover, and removing chest and crotch buckles from the straps. Replacing the cover requires rethreading the straps through the seat cover openings, properly orienting and rethreading all the buckles, then finally reinstalling the car seat into the car.
U.S. Pat. Nos. 4,883,701 and 4,891,454 disclose disposable or reusable liners with slits and perforations allowing the liner to fit into many different car seat shapes. Depending on the car seat configuration, the shoulder straps may still have to be threaded through openings in the liner. The disposable liners disclosed in U.S. Pat. Nos. 4,883,701 and 4,891,454 do not fully cover and protect the factory cover, but rather protect just the seating portion of the padded cover. A need exists for an attractive, easily replaceable car seat cover that does not require removing or rethreading the shoulder straps or removing the seat from the car or stroller.
SUMMARY OF THE INVENTION
The removable car seat cover that meets the need identified above installs over the car seat and existing padded upholstery. The removable cover comprises a periphery that secures the cover to the edges of a car seat. Openings in the cover allow shoulder straps and one or two crotch straps to extend through the cover while the ends of the straps remain affixed to the car seat.
One embodiment of the cover has two vertical openings allowing shoulder straps of a five-point or six-point harness system to extend through the cover. Optionally, a second panel of cover material can be affixed to the cover such that it covers the openings between the points where the top and bottom portions of the shoulder straps extend through the cover.
Another embodiment of the cover has a “U” shaped opening allowing shoulder straps of a three-, five- or six-point harness system to extend through the cover. A fastener, such as Velcro, can hold the fabric on each side of the “U” shaped opening together. Optionally, a flat panel attaches behind the upper portion of the “U” shaped opening. The top of the flat panel attaches to the back of the cover above the top end of the “U” shaped opening. The bottom of the flat panel attaches to the portion of the cover between the slits defined by the “U” shaped opening. The left and right side of the flat panel each have one or more elasticized horizontal slits, which close around the shoulder straps passing through the panel. The outer ends of the horizontal slits fasten together with a snap or other fastener.
Another embodiment of the seat cover uses two or more horizontal openings that extend across the back of the seat cover, wherein the horizontal patches of cover material between the openings come apart vertically, the two sides held by a fastener. The shoulder straps of a three-point harness system will extend through an upper horizontal opening. By opening the fasteners holding the two sides, shoulder straps in a five- or six-point harness system extend through an upper and lower horizontal opening. Refastening the two sides keep the back of the seat cover flat.
For car seats with a canopy, the car seat cover includes a matching canopy cover. The canopy cover has an additional panel that hangs over the front or back edge of the canopy for shading the infant.
Another embodiment of the seat cover has openings for the shoulder belt positioning mechanism on a booster seat.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Common car seat configurations are shown in FIGS. 1A, 1B, 1C, 1D and 1E. FIG. 1A shows toddler seat 100 with a 5-point harness. Shoulder straps 110-1 and 110-2 attach at upper anchor points 114-1 and 114-2 above the child's shoulders and at lower anchor points 116-1 and 116-2 near the child's hips. Crotch strap 120 with buckle 121 attaches at anchor point 118 between the child's legs. Buckles 111-1 and 111-2 on the shoulder straps connect to buckle 121 on crotch strap 118 to secure the child. Some car seats use a six-point harness, which is configured like a five-point harness, but with a second strap and buckle at the crotch. FIG. 1B shows toddler seat 101 with a 3-point harness. Often, a single belt of material forms both shoulder straps 110-1 and 110-2. One end of strap 110-1 attaches to anchor point 114-1 above one shoulder. Strap 110-1 extends down towards the crotch, threads though buckle 111, and (now as strap 110-2) extends up and attaches to anchor point 114-2 by the other shoulder. Buckle 121 attaches to crotch strap 120. Crotch strap 120 attaches to the seat at anchor point 118. Buckle 111 attaches to buckle 121 to secure the child. FIG. 1C shows infant seat 102 with a 3-point harness. Shoulder straps 110-1 and 110-2 attach at upper anchor points 114-1 and 114-2 above the child's shoulders and come together, attaching at buckle 111. In this embodiment, crotch buckle 121 attaches directly to anchor point 118 without a crotch strap. Buckle 111 attaches to buckle 121 to secure the child. FIG. 1D shows infant seat 103 with a 5-point harness. Shoulder straps 110-1 and 110-2 attach at upper anchor points 114-1 and 114-2 above the child's shoulders and at lower anchor points 116-1 and 116-2 near the child's hips. Crotch strap 120 with buckle 121 attaches at anchor point 118 between the child's legs. Buckles 111-1 and 111-2 on the shoulder straps connect to buckle 121 on crotch strap 120 to secure the child. Car seats with a 6-point harness have a second crotch strap and crotch buckle attached at anchor point 118. FIG. 1E shows booster seat 104 with shoulder belt positioning clips 130. Shoulder belt 135 passes through shoulder belt positioning clips, allowing an automobile seat belt to properly restrain children. Some booster seats use slots or other openings rather than clips to position the shoulder belt.
FIG. 2 shows a removable car seat cover 250 for use with 5-point or 6-point harnesses. Although FIG. 2 shows a toddler seat cover, one skilled in the art will readily understand how to adapt the invention to an infant seat. The cover is comprised of a washable fabric, and may have a plurality of layers.
