KNEE PROTECTIVE DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a knee protective device capable of precisely protecting not only knees but also shins under the knees at the time of vehicle collision. SOLUTION: The knee protective device S is provided with a knee protective panel 21 which is drawn out to a front side of the knees of an occupant by a driving mechanism at the time of the vehicle collision and restrains the knees moving forward to absorb kinetic energy of the knees. The knee protective panel 21 has a vertical dimension for interfering with the knees and shins under the knees of the occupant, and is constituted so that a shock absorbing part 25 plastically deformed when interfering with the knees and shins to absorb the kinetic energy thereof is provided. The shock absorbing part 25 is constituted so that a load in plastic deformation for reducing vertical thickness is set to be larger on an upper part 25a side interfering with the knees than that on a lower part 25b side interfering with the shins.
