AI Technical Summary

Technical Problem

Motorcyclists often fail to notice the activation of their turn signals in time, leading to potential collisions due to their focus on the road and other road users, which existing visual indicators are insufficient to prevent.

Method used

Integrating a vibration motor into the handlebar grips that activates when the turn signal is switched on, providing a tactile reminder to the rider.

Benefits of technology

Enhances accident prevention by ensuring the rider switches off the turn signal promptly, reducing the risk of collisions at intersections.

Description

[0001] Device for preventing accidents involving all common motorized two-wheelers (motorcycle, e-bike, pedelec, e-scooter, etc.) by vibrating the handlebar grips when the turn signal is activated. See drawing. Fig. 1, installed in the inner end of the handle rubber sleeve. See drawing. Fig. 2. Installed in the wrist rest of the grip rubber. Both are embedded in the grip rubber material or integrated during manufacturing.

[0002] The grip is designed to protect a handlebar grip containing an integrated vibration motor that vibrates when the turn signal is activated. These handlebar grips fit all common motorized two-wheeler handlebars.

[0003] This function serves as an additional reminder to the original visual indicator and thus enhances accident prevention. Because motorcyclists are often focused on the road and other road users, the visual indicator is frequently noticed too late, and the turn signal remains unnecessarily activated, which can lead to dangerous misunderstandings. Activating the turn signal flasher simultaneously activates the vibration motor in the handlebar ends. The motorcyclist perceives this vibration and is reminded to switch off the turn signal. This minimizes the risk of another road user at the next intersection or junction assuming the motorcyclist intends to turn right when they are continuing straight ahead, thus preventing a potentially serious collision.

Claims

[1] A handlebar grip that fits all common motorized two-wheeler handlebars. This handlebar grip is equipped with vibration motors that vibrate when the turn signal is activated. This vibration is transmitted to the rider's hand, reminding them to turn the turn signal off. The handlebar grips are compatible with all common motorized two-wheeler handlebars. [2] A function designed to alert the rider of motorized two-wheelers, in addition to the original visual turn signal indicator, that the indicator is switched on, thus contributing to increased accident prevention. Because the rider is often concentrating on the road and other road users, the visual indicator is frequently noticed too late, and the turn signal remains unnecessarily activated, which can lead to dangerous misunderstandings. Activating the turn signal simultaneously activates the vibration motor in the handlebar grips. The rider perceives this vibration and is reminded to switch off the turn signal. This minimizes the risk that another road user at the next intersection / junction might assume the rider intends to turn right when they are continuing straight ahead, thus avoiding the resulting high risk of a collision.
