Abstract
A shock absorber for a vehicle seat belt comprises a flexible crushable pad adapted to be positioned between the shoulder strap of a seat belt and the shoulder of a user. Separable attachment means secures the crushable pad in a predetermined position in relation to a seat back. The attachment means permits movement of the pad further from said seat back on application of a predetermined force, e.g. in an accident.
Claims2
A shock absorber in combination with a child's safety seat having a shoulder strap projecting through a slot in the seat back, comprising a flexible crushable pad adapted to be positioned between the shoulder strap of a seat belt and the shoulder of a user, and a clip arranged to engage in said slot to secure the crushable pad in a predetermined position in relation to a seat back, the clip being adapted to become detached to permit movement of the pad further from said seat back on application of a predetermined force, wherein the pad is mounted on a flexible backing and the clip comprises an extension of the flexible backing having a T-shaped formation on its end which engages beyond the ends of the slot.
A child's vehicle seat having a seat back, a seat belt for said seat including a shoulder strap projecting through a slot in said seat back, and a shock absorber comprising a flexible crushable pad slidably mounted on the shoulder strap so as to be positioned between the shoulder strap and a user's shoulder, and a T-shaped formation on one end of the pad, the T-shaped formation projecting through and engaging beyond the ends of the slot in the seat back to maintain the crushable pad in a predetermined position relative to the seat back as the seat belt is fastened, the T-shaped formation being adapted to become detached from the slot so as to permit movement of the pad further from said seat back on application of a predetermined force so that the pad is maintained in a substantially constant position relative to the user by friction between the pad and the user's shoulder in the event of forward movement of the user's shoulder relative to the seat back.
