Abstract: A patient restraint device for restraining invalid patients and the like. A generally unitary vest body has two face portions merging at the shoulder, and a neck opening formed between the shoulders. Each of the face portions has a distal edge formed at the ends of the faces furthest removed from the neck opening. Each of the faces terminates at the distal edge portion in straps. Two such straps are provided for each of the faces, one at each side edge thereof. The distal edge of one of the faces is longer than the distal edge of the other of the faces. An opening is formed in the face having the longer of the two distal edges, and adapted to receive at least two of the straps. The opening is a single vertical slot positioned just above and at the center of the distal edge of the face having the longer distal edge.
