A vehicle retractable step assembly includes a support member, a support arm, a step member and a restricting assembly. The support member is configured to attach to a vehicle body structure. The support arm has a first end and a second end. The first end is supported to the support member for pivoting movement with respect to the support member. The step member is attached to the second end of the support arm for pivotal movement relative to the second end of the support arm between a retracted orientation where the step member is located adjacent to the support member and an extended orientation where the step member is spaced apart from the support member. The restricting assembly is releasably attached to the support member and positioned to prevent pivoting movement of the support arm relative to the support member.

1. A vehicle retractable step assembly, comprising: a support member configured to attach to a vehicle body structure;a support arm having a first end and a second end, the first end being attached to the support member for pivoting movement with respect to the support member;a step member attached to the second end of the support arm for pivotal movement relative to the second end of the support arm between a retracted orientation where the step member is located adjacent to the support member and an extended orientation where the step member is spaced apart from the support member, the pivotal movement between the retracted orientation and the extended orientation defining an arcuate path and a corresponding angle; anda restricting assembly releasably attached to the support member such that with the restricting assembly attached to the support member the restricting assembly is positioned to limit pivoting movement of the support arm relative to the support member reducing the size of the arcuate path and the corresponding angle, and with the restricting assembly removed from the support member the support arm can pivot along the arcuate path and the corresponding angle. 2. The vehicle retractable step assembly according to claim 1, wherein the restricting assembly includes a first block and a vibration dampening member, the first block being attached to the support member and the vibration dampening member being attached to the first block such that the vibration dampening member directly contacts the support arm. 3. The vehicle retractable step assembly according to claim 2, wherein the vibration dampening member is made of a resilient and compressible material. 4. The vehicle retractable step assembly according to claim 2, wherein the first block is made of a rigid material that includes a frangible portion such that in response to an impact having a predetermined level of force, the first block breaks along the frangible portion into at least two separate pieces. 5. The vehicle retractable step assembly according to claim 1, wherein the support member includes a first stop surface and a second stop surface that are positioned to limit movement of the support arm such that with the support arm located adjacent to the first stop surface the step member is in the retracted orientation and with the support arm located adjacent to the second stop surface the step member is in the extended orientation. 6. The vehicle retractable step assembly according to claim 5, wherein the first stop surface and the second stop surface are positioned with respect to one another such that the support arm defines an arcuate path of between 40 and 80 degrees as measured between the retracted orientation and the extended orientation. 7. A vehicle retractable step assembly comprising: a support member configured to attach to a vehicle body structure;a support arm having a first end and a second end, the first end being attached to the support member for pivoting movement with respect to the support member;a step member attached to the second end of the support arm for pivotal movement relative to the second end of the support arm between a retracted orientation where the step member is located adjacent to the support member and an extended orientation where the step member is spaced apart from the support member;the support member including a first stop surface and a second stop surface that are positioned to limit movement of the support arm such that with the support arm located adjacent to the first stop surface the step member is in the retracted orientation and with the support arm located adjacent to the second stop surface the step member is in the extended orientation; anda restricting assembly releasably attached to the support member and positioned to limit pivoting movement of the support arm relative to the support member, the restricting assembly including a first block and a vibration dampening member, the first block being attached to one of the first stop surface and the second stop surface, the vibration dampening member being attached to the first block such that the vibration dampening member directly contacts the support arm. 8. The vehicle retractable step assembly according to claim 7, wherein the vibration dampening member is made of a resilient and compressible material. 9. The vehicle retractable step assembly according to claim 7, wherein the first block has a first surface that contacts one of the first stop surface and the second stop surface of the support member and a second surface having the vibration dampening member attached thereto, the first surface being on an opposite side of the first block from the second surface, the first surface being angularly offset from the second surface by an angle that is between 15 degrees and 50 degrees. 10. A vehicle retractable step assembly, comprising: a support member configured to attach to a vehicle body structure;a support arm having a first end and a second end, the first end being attached to the support member for pivoting movement with respect to the support member;a step member attached to the second end of the support arm for pivotal movement relative to the second end of the support arm between a retracted orientation where the step member is located adjacent to the support member and an extended orientation where the step member is spaced apart from the support member;the support member including a first stop surface and a second stop surface that are positioned to limit movement of the support arm such that with the support arm located adjacent to the first stop surface the step member is in the retracted orientation and with the support arm located adjacent to the second stop surface the step member is in the extended orientation; anda restricting assembly releasably attached to the support member, the restricting assembly including a first block, a second block, a first vibration dampening member and a second vibration dampening member, the first block being attached to the first stop surface, the second block being attached to the second stop surface, the first vibration dampening member being attached to the first block and the second vibration dampening member being attached to the second block such that the support arm is confined between the first vibration dampening member and the second vibration dampening member. 11. The vehicle retractable step assembly according to claim 10, wherein the first and second vibration dampening members are made of a resilient and compressible material. 12. The vehicle retractable step assembly according to claim 10, wherein the first block has a first surface that contacts the first stop surface and a second surface supports the first vibration dampening member, the first surface being angularly offset from the second surface by a first angle,the second block has a third surface that contacts the second stop surface and a fourth surface supports the second vibration dampening member, the third surface being angularly offset from the fourth surface by a second angle, the sum of the first angle and the second angle being between 30 degrees and 75 degrees. 13.
