High chair
High chairs are used to seat infants who are too small to be seated in standard chairs. A typical high chair simulates for the small child the experience of eating at a table as the high chair provides a seat and a tray supported by arm members so as to maintain the tray in a position adjacent to the seat. The tray functions as a table top or counter top upon which food receptacles and utensils are normally placed. High chairs have a seat for the infant or young child, and have a tray upon which the child's meal is placed. The tray is securely coupled to the frame of the chair. High chairs are typically provided with a tray spanning the arms of the chair in front of the infant. The tray serves to restrain the infant within the chair and provide a horizontal surface for holding food during feedings or toys or the like at other times. These chairs are usually designed for children who are able to sit upright without assistance. There are many different designs for these high chairs and they may be formed from many different materials, such as wood, metal or plastic. A highchair is known to comprise a tray on which toys can be placed or on which a container can be positioned holding a food to be administered to the child (such as a plate with a meal or a beaker of water). Typically, such high chairs include a seat with a seat bottom, a seat back, and some form of side barriers. The seat typically is supported by four legs affixed thereto. A detachable tray normally provided with the highchair is either selectively attachable and detachable from both arms of the chair for complete removal of the tray or is pivotably attached to one arm and attachable and detachable from the opposite arm so that the tray can be pivoted off of the child to allow the child to be removed from the high chair. Another type of seat used for feeding children is commonly known as a booster seat and includes a seat bottom, a seat back, and possibly side barriers. The booster seat is typically placed on an adult-sized chair and may serve to "boost" the child up to an appropriate height for eating at a table. Another type of highchair arrangement to allow a child to eat at a counter or table is a clip-on seat, which includes a seat having a seat bottom, a seat back, and side barriers, with elongated arms extending from the side barriers. The elongated arms have portions which are placed above the planar surface of the table and have other portions which are placed below the planar surface of the table to grasp the table between the portions of the extended arms. In some designs a tray is provided with the high chair to provide a surface that the child can easily access. The chairs may be collapsible for storing or may have a non-collapsible fixed frame. Oftentimes straps, belts or other means are provided with the chair to secure the child in place. High chair trays allow the tray to be removed to facilitate placing the infant in the high chair and removing him or her therefrom. These mechanisms generally comprise two latches or detent means, one on each side of the bottom surface of the tray, which are spring biased into corresponding slots or recesses incorporated into the arms of the chair. n order to prevent the child from slipping or submarining out of the chair underneath the tray, some high chairs include some sort of restraint system which is typically a belt and buckle arrangement for fastening about the waist of the infant and preventing movement of the infant out of the seat without disconnecting the belt system.
