The wheelchair comprises a wheel carrier of a fork (3), two limbs (6,7) and transverse web, pivotally connected to a pivotable body to allow for tilting in the horizontally axis (14). An elastic spring (21) is arranged between the wheel and carrier to counter the tilting movement, and a setting member (23) provides a preload to the spring, such that the carrier can only tile once it has been overcome. |
