A column cover unit may include: a column cover configured to cover a steering column of a vehicle and comprising a first cover portion and a second cover portion, wherein a boundary between the first cover portion and the second cover portion extends from a front end of the column cover at a front portion of the vehicle toward a rear portion of the vehicle; and a contact member configured to separate the first cover portion and the second cover portion from each other at the boundary by contacting the column cover when the column cover is moved toward the front portion of the vehicle with the steering column.

The shock absorber includes: a base portion fixed to the attachment target; a shock absorbing portion having flexibility and attached to the base portion so as to be reversibly switchable between a housed state in which the shock absorbing portion is retracted toward the base portion and a protruding state in which the shock absorbing portion protrudes from the base portion; and a drive unit driving the shock absorbing portion to reversibly switch between the housed state and the protruding state. The drive unit, when operating the shock absorbing portion, at least switches the shock absorbing portion from the housed state to the protruding state.

A lateral shock absorber includes a protective fender and a locking mechanism. The protective fender is pivoted to a base of a child car safety seat and pivotally switchable between a folded state or an unfolded state relative to the child car safety seat. The locking mechanism is for selectively engaging with the protective fender to restrain the protective fender from switching to the unfolded state or disengaging from the protective fender to allow the protective fender to switch to the unfolded state when the protective fender is located in the folded state. The protective fender includes a driving block, a supporting block and a combining assembly. The driving block is pivoted to the base, and the supporting block is pivoted to the driving block and engages with the driving block by the combining assembly.

The occupant protection device that protects an occupant boarding on a vehicle and includes: a base portion fixed to the vehicle; an operation portion connected to the base portion and configured to move back and forth between a first position serving as an initial position and a second position used to suppress movement of the occupant when inertial force acts on the occupant; and a control unit configured to perform movement control to move the operation portion from the first position to the second position. The operation portion is movable repeatedly from the first position to the second position through the movement control by returning to the first position after having moved from the first position to the second position. The occupant protection device includes an buffering means configured to buffer a collision impact on the occupant against the operation portion when the operation portion moves to the second position.

A vehicle occupant protection device includes a vehicle seat, a steering wheel, a steering moving mechanism, and a control unit. The vehicle seat includes a seat back and a headrest, the vehicle seat being configured to turn between a position where the vehicle seat is directed toward a vehicle front side and a position where the vehicle seat is directed toward a vehicle rear side. The steering wheel is provided ahead of the vehicle seat in a vehicle front-rear direction. The steering moving mechanism is configured to change a position of the steering wheel. The control unit is configured to move the steering wheel to a support position where the seat back and the headrest are supported by the steering wheel from the vehicle front side, by the steering moving mechanism, when the vehicle seat is directed toward the vehicle rear side.

A knee airbag for vehicles is provided. The knee airbag includes a lower crash pad that has a panel shape to block a steering column to prevent exposure of the steering column to an indoor space of a vehicle, and includes a housing unit having recesses dented toward the steering column such that the housing unit is spaced apart from the steering column by a designated distance. An airbag module of the knee airbag includes an inflator and a cushion and contained in the housing unit of the lower crash pad to deploy the cushion toward a driver's knee outside the lower crash pad when the cushion is deployed by explosion of the inflator.
