## Abstract

A safety handle designed to be fitted onto a tubular element of an item of mobile equipment, comprises at least one signaling means. The handle further comprises a radio frequency communication module and an electronic circuit for controlling the communication module by a signal of a change in direction.

## Claims

### Claim 1

A safety handle configured to be fitted to a handlebar of an item of mobile equipment, comprising at least one signaling device comprising:
a radio frequency communication module;
an electronic circuit for controlling the communication module; and
a part that is stowable between a first position where one end of the part is equipped with a light signaling source that protrudes from a surface of the handlebar and a stowed second position, the light signaling source being controlled by the radio frequency communication module and the electronic circuit responsive to a signal of a change of direction.

### Claim 2 (depends on 1)

The safety handle of claim 1, wherein the communication module is configured to exchange data with a smartphone.

### Claim 3 (depends on 1)

The safety handle according to claim 1, wherein the communication module is configured to exchange data with a road network management infrastructure.

### Claim 4 (depends on 1)

The safety handle of claim 1, further comprising an energy collection device configured to supply power for the electronic circuit and the communication module.

### Claim 5 (depends on 4)

The safety handle of claim 4, wherein the energy collection device comprises a piezoelectric generator or an electromagnetic generator.

### Claim 6 (depends on 5)

The safety handle of claim 5, further comprising an actuator for controlling the movement of the stowable part.

### Claim 7 (depends on 1)

The safety handle of claim 1, wherein the light signaling source protrudes from a front surface of the handlebar in the first position.

### Claim 8 (depends on 1)

The safety handle of claim 1, further comprising a haptic surface area controlled by the electronic circuit as a function of change of direction information coming from a navigation application run by the electronic circuit or by a smartphone communicating with the radio frequency communication module.

### Claim 9 (depends on 1)

The safety handle of claim 1, further comprising a gyroscopic sensor delivering a signal controlling the activation of the signaling device via the electronic circuit.

### Claim 10 (depends on 1)

Handlebar A handlebar comprising a safety handle according to claim 1, comprising a locking mechanism for locking the stowable part of the safety handle in the stowed position.
