Abstract: A footrest is provided to restrain a passenger's ankle from bending backward at a vehicle front collision. When a toe board 2b is deformed toward a passenger's room at the vehicle front collision, then a frame member 7 forming an energy absorbing unit 5 for the footrest 3 begins to be deformed on compression. In the member's deformation, a front-inclined leg part 9F of the member 7 on the side of the passenger's toe yields ahead of others firstly. Thus, the compressive deformation is successively transmitted from the frame member's part on the side of the passenger's toe to the same part on the side of the passenger's heel frame member 7, so that collision energy can be absorbed to moderate an impact exerted on the passenger's foot F. Additionally, since the foot F is moved obliquely upward of the toe board 2b by the prior deformation of the part 9F, it is possible to restrain the passenger's ankle from bending backward.

Abstract: The I/O bracket retainer of the present invention is a unitary structure that provides excellent EMI shielding without the requirement of an additional gasket layer. EMI leakage is minimized by providing an I/O bracket retainer surface, typically stainless steel, that conforms to the surface of the I/O bracket retainer and I/O panel, thus minimizing seams formed due to small differences in the planarities of the I/O bracket retainer and I/O panel. EMI leakage is further reduced by providing firm contact between the surfaces of the I/O bracket retainer and I/O panel to minimize seam formation between these parts. Firm contact is provided in part by a first positioning tab and spring finger which extend from a sidewall of the structure to the front panel of the I/O bracket retainer. The front panel of the I/O bracket retainer is designed for receiving and securing an I/O panel.
