A squeeze film damper includes a bearing housing as an inner ring disposed around a radially outer side of a bearing which rotatably supports a rotary shaft, an outer ring disposed around a radially outer side of the bearing housing, a squeeze film formed by circulating a viscous fluid through a clearance in a radial direction between the bearing housing and the outer ring, and a coupling pin which couples the bearing housing and the outer ring to each other and is deformable in response to relative displacement in the radial direction between the outer ring and the bearing housing. The coupling pin has stiffness that is higher in a vertical direction than in a horizontal direction in a cross section perpendicular to an axial direction of the rotary shaft.

The present invention relates to a knee protector structure for a vehicle. The present invention intends to make it possible to positively prevent an upper absorption bracket from being deformed with a tensile force exerted through a connecting bracket when a lower absorption bracket is deformed with knee input energy of a small-statured vehicle occupant. The knee protector structure for a vehicle according to the present invention comprises a lower absorption bracketable to absorb knee input energy of a small-statured vehicle occupant, an upper absorption bracketable to absorb knee input energy of a vehicle occupant of an average constitution, a connecting bracketfor connection between input-side end portionsandof the lower absorption bracketand the upper absorption bracket, and tensile force absorbing meansdisposed near the input-side end portionof the upper absorption bracketand able to absorb a tensile forceexerted from the connecting bracket

Knee protector structure for vehicle

A knee bolster structure includes a vehicle-side member, a knee-receiving member, an impact-absorbing section for absorbing an input energy from knees of a driver or front-seat passenger when the knees hit the knee-receiving section, and a knee-receiving member movement section for moving the knee-receiving member to a knee-receiving position for the driver or front-seat passenger, said knee-receiving member being attached to the vehicle-side member via the impact-absorbing section and the knee-receiving member movement section, the impact-absorbing section being structurally separated from the knee-receiving member movement section.

Knee bolster structure

A knee bolster structure includes an upper shock-absorbing member adapted for absorbing input force of knees of an occupant who has an average physical constitution and a lower shock-absorbing member adapted for absorbing input force of knees of an occupant who is small in stature, and a difference in strength between the upper shock-absorbing member and the lower shock-absorbing member is provided such that receiving strength of the upper shock-absorbing member is larger and receiving strength of the lower shock-absorbing member is smaller.
