Abstract

A measuring device ( 10 ) for measuring the space remaining after a side crash has a pneumatic piston rod cylinder ( 20 ) with a cylinder ( 22 ), and a piston rod ( 24 ) that can move relative to the cylinder ( 22 ). A measuring unit ( 40 ) measures the movement ( 26 ) of the piston rod ( 24 ) relative to the cylinder ( 22 ), and a base part ( 12 ) positions the piston rod cylinder ( 20 ). The piston rod cylinder ( 20 ) can be connected to a pressure vessel ( 70 ) to permit the piston rod ( 24 ) to move out when a fluid is applied to the piston rod cylinder ( 20 ).

First claim

What is claimed is:

1. A measuring device for measuring the space remaining after a side crash, the measuring device comprising: a pneumatic piston rod cylinder with a cylinder, and a piston rod that can move relative to the cylinder; a measuring unit for measuring the movement of the piston rod relative to the cylinder; and a base part for positioning the piston rod cylinder, the piston rod cylinder can be connected to a pressure vessel to permit the piston rod to move out when a fluid is applied to the piston rod cylinder.

2. The measuring device of claim 1 , further comprising a pressure-reduction valve that is configured to limit the pressure in the piston rod cylinder to a predefined pressure.

3. The measuring device of claim 2 , in which the predefined pressure is adjustable.

4. The measuring device of claim 1 , further comprising plates with a predefined area provided at each of the ends of the piston rod cylinder.

5. The measuring device of claim 4 , wherein the plates are detachably connected to the piston rod cylinder to permit the plates to be exchanged.

6. The measuring device of claim 1 , further comprising a controllable valve that is designed to activate or deactivate the admission of the fluid to the piston rod cylinder.

7. The measuring device of claim 1 , further comprising a guide that permits a linear movement of the base part relative to the cylinder.

8. The measuring device of claim 1 , configured as a portable unit in which the base part, the piston rod cylinder and the pressure-reduction valve are connected to one another.

9. The measuring device of claim 1 , further comprising a pressure vessel.

10. The measuring device of claim 1 , further comprising a detachable connection provided on the base part to permit the pressure vessel to be connected to the base part.

11. The measuring device of claim 1 , further comprising handles on the base part.
