Abstract
Description
[0001] 1. The invention relates to an additional mechanical safety element designed as a self-contained buckle with a conical metal tip. This special buckle can be attached to an existing car seat belt buckle and extends its function by several safety-relevant features.
[0002] 2. The conical metal tip is primarily designed to break car windows with a targeted blow in emergency situations – for example, after an accident or if water enters the vehicle – allowing for a quick exit from the vehicle. Unlike conventional emergency hammers, this device is permanently connected to the seatbelt and therefore always readily accessible, even if the vehicle occupant is trapped or cannot reach the dashboard or glove compartment.
[0003] 3. Additionally, the extra buckle provides an alternative way to open the seatbelt. Should the main buckle become blocked or jammed due to a mechanical defect, the belt can be safely released using the additional buckle.
[0004] 4. Another advantage is the extended strap length: The additional buckle creates a small gap between the strap and the body. This feature is particularly beneficial for pregnant women, as it reduces pressure on the abdomen, thus increasing comfort and safety.
[0005] 5. The conical metal tip can be manufactured cost-effectively and efficiently using CNC turning or series production. It is attached to the auxiliary buckle via a precisely pre-drilled hole and a force-fit connection, supplemented by a high-quality industrial adhesive. A clean mechanical connection is ensured without the need for welding or further surface treatment, making production simple and economical.
[0006] 6. The invention is modular in design, can be retrofitted in series production vehicles and represents a practical, immediately usable addition to existing vehicle safety.
Claims
[1] Seat belt buckle with integrated striking head, characterized by , that the belt buckle has a fixed, conical steel attachment (1) which serves as an emergency striking tool for breaking vehicle windows. [2] The steel attachment according to claim 1 is firmly integrated into the outer housing of the belt buckle and does not impair the mechanical function or the operability of the buckle. [3] The striking head according to claim 1 is ergonomically designed and of a size that allows stable placement in the palm of the hand and thus ensures more precise and powerful application. [4] The belt buckle according to claims 1-3 is particularly suitable for users with special physical conditions, including pregnant women and overweight persons with a larger waist circumference, to ensure easy handling and effective use in emergencies.
