<p>A system for inhibiting a wheeled, personal mobility unit from sliding along a surface having two or more surface portions oriented at mutually different angles has at least one part (10) having a contact surface (12) that generally complements the two or more surface portions. The part (10) also has a body (14) extending from the contact surface (12) and terminating at an exposed surface. The part may have hinges (22, 24) to enable the part to bend and conform to complement the surface. The part may have three dimensional features (42) extending from the contact surface (12) for increased adhesive contact area relative to a flat contact surface. The part is anchored to the surface by means of offset fastening members (69) extending from the contact surface (12) and into a substrate of the surface.</p> |
