US Patent 7874613 Chair stabilizer and method of use

A chair stabilizer for preventing injury to children or others who might tip over chairs. A removable chair-engaging section is removably and adjustably couplable to a table-engaging section. Generally, the entire apparatus is free standing but in conjunction with a flat or available undersurface, the table-engaging portion prevents rearward rotation of the chair as the table-engaging portion comes into contact with the underside of the flat surface, such as a table when the chair-engaging section is rotated. As a result, vulnerable individuals including children and the infirm are protected from impact with the ground should the chair begin tipping as the table restrains the rotational motion of the chair.
