Arrangement for holding seat belt anchor band

An arrangement for detachably fixing a buckle-mounted anchor band of a seat belt to a given portion of a seat back of a seat, comprising:

• a holder tightly connected to said seat back and provided at laterally opposed sides with respectively outwardly protruding flanges;
• and
• a cover member housing therein the buckle of the anchor band and fixed thereto to move therewith, said cover member being constructed to a resiliently deformable plastic and formed with a longitudinally extending slot which comprises first, second and third parts arranged to provide said first part having a width which is greater than the distance between the outwardly protruded flanges of said holder, said second part having a width which is so sized as to slidably hold said outwardly protruded flanges by opposed flange portions thereof and said third part having opposed projections and a width which is smaller than the distance between said outwardly protruded flanges and extending to a terminal open end of said slot,
• whereby when, with said holder being coupled with said slot of the cover member, a force greater than a predetermined degree is applied to said holder to move the same in a direction from said second part to said third part, said opposed projections of said third part are resiliently deformed to release said holder from said slot.
