Safetybelt

In order to meet today's needs in the automobile, we have reconsidered the safety belt and developed it from scratch. The entire mechanism locates in the lock on the webbing. The seat is only a form-locking integrated socket pin. Thanks to the rotatable magnet in the lock, it automatically exits as soon as the belt approaches. This allows one-handed and blind operation. The gentle click is confirmed with a noticeable and audible feedback. The positive connection bears a tensile load of up to 1.5 tonnes, which is a normal burden in an accident. The loosening of the belt is also simple, ergonomic and done with just one hand. If the two red buttons are pressed simultaneously, the clamps in the lock open, the magnet turns 180 degrees and pushes the bolt back into the seat.

The three-point belt has been in use for over 50 years. Whether in the Rolls Royce or the Fiat - everywhere he looks the same. Since its introduction, the principle has not changed. It is neither ergonomic nor barrier-free to operate. The tongue is small and poorly palpable. The counterpart is mostly hidden and hitting the slot proves to be true art. Also, the release is only cumbersome and possible with two hands. In addition, the existing seat belt is a danger to children because they can easily solve it by pressing the button. These are reasons enough to revolutionize the safety belt after 50 years.

We analyzed the entire safety system in the automobile and fundamentally rethought it. Using an actual and an ideal scenario of use, we were able to create a detailed requirement list, from which three approaches were conceived. Based on a list of criteria, the optimal solution emerged, which we finally developed in detail. After countless formal studies, the design of the mechanism proved to be a crucial element in designing the outer shape. Consequently, we worked two lanes, from outside and inside each other until we reached the optimal interaction. Our idea worked on the computer model and finally the printed prototype confirmed our solution approach. Let us save life - your life!
