Abstract: Shade apparatus for a vehicle are disclosed. A disclosed the shade apparatus for a vehicle windshield includes a shade movable along the windshield in a front-rear direction of the vehicle. The shade apparatus also includes a drive unit to move the shade. The shade includes a groove portion to accommodate a room mirror mounted on the windshield and the groove portion extend from the front end of the shade toward the rear of the shade.

Abstract: Vehicle rigidity apparatus for a vehicle are disclosed. A disclosed the vehicle rigidity apparatus for a central frame that extends in a lateral direction of the vehicle and lateral frames that extend in a front-rear direction of the vehicle and intersect the central frame. The vehicle rigidity apparatus also includes a reinforced bar that extends in the lateral direction of the vehicle supported by the lateral frames, the reinforced bar being movable from a position at the central frame toward a front of the vehicle in the front-rear direction and a movable portion at the central frame that moves the reinforced bar toward the front of the vehicle. The movable portion moves the reinforced bar toward the front of the vehicle to a position separated from the central frame.

Abstract: A walk-in apparatus for a seat of a vehicle, including an upper rail connected to the seat; a lower rail connected to a floor of the vehicle; a lead screw connected to the lower rail; a male helical gear connected to the lead screw, the male helical gear including external splines; and a female helical gear connected to the upper rail. The female helical gear includes internal splines configured to engage with the external splines of the male helical gear, and the male helical gear and the female helical gear are selectively separable. A torque transferred between the internal splines of the female helical gear and the external splines of the male helical gear when connected moves the upper rail relative to the lower rail.
