Patent Images
1. A curb cushion comprising:
- a first end portion and a second end portion;
a top surface extending over the first end portion and the second end portion;
a bottom surface including a lower bottom surface extending under the first end portion and an upper bottom surface extending under the second end portion, the upper surface being offset from the lower surface in a direction towards the top surface; and
a deformable body portion extending between the top and bottom surfaces, the body portion being constructed of a resilient deformable material.

Abstract
The cushion according to one embodiment is a deformable resilient apparatus with a surface for allowing various vehicles to transverse from a first surface to a second surface that are separated by an obstacle without damaging the obstacle. The cushion deforms to fit the space between the vehicle and the obstacle, thereby preventing concentration of stress on the obstacle. The cushion is constructed such that it does not slide out of place when engaged by tracks or wheels of a vehicle. The cushion is constructed to deform and distribute the force applied by the vehicle onto the object more uniformly.
