Abstract: A boarding and alighting step-mounted vehicle includes an entrance provided in a vehicle side portion, a sliding door having two door portions for opening and closing the getting-on/off port by sliding in directions opposite to each other in the vehicle front-rear direction, and a step body having a step body for allowing an occupant to step when getting on and off the vehicle. The step is switchable between the use state and the closed state by rotating the vehicle lower portion on the entrance side as a pivot axis. In the use state of the step, the step body is in a posture deployed outward of the vehicle. In the closed state of the step, the step body is closed on the vehicle side and is in a posture facing the sliding door.

The seat is provided inside a vehicle cabin, and the airflows circulate around the seating space as viewed from a front side of the seat.

Abstract: A handrail member is in a deployed state and at a so-called usable position when a tip portion of the handrail member is arranged between a sliding door and a lateral portion of a vehicle. Moreover, by making the handrail member usable, a passenger can place his or her hand on the handrail member when getting on or off the vehicle. As a result, it is possible to help the passenger get on/off the vehicle. In this manner, by turning the handrail member along a vehicle width direction around a bolt, the handrail member can be deployed and stored with a simple configuration.

Abstract: An occupant protection device includes a multidirectional airbag that inflates and deploys from a state housed in a headrest on receipt of supplied gas. The multidirectional airbag is configured as an integral bag body to surround a head of a seated occupant with a front deployment section and a pair of left and right lateral deployment sections. The front deployment section includes a front inflating portion that deploys to a seat forward direction of the head of the seated occupant and of at least one of a shoulder or chest of the seated occupant. Each of the pair of left and right lateral deployment sections includes a lateral inflating portion that is connected to the front deployment section and inflates and deploys alongside the head of the seated occupant.

Abstract: There is provided a vehicle occupant protection device, the device including (1) a rear detection section that detects an object approaching obliquely from a rear of an occupant's vehicle, (2) a signal output section that outputs an actuation signal, and (3) a seatbelt device that includes a mechanism to, in cases in which the object has been detected by the rear detection section, increase restraint force on an occupant by taking up webbing after being input with the actuation signal.

Abstract: A vehicle pre-crash seat belt device includes: a buckle moving mechanism that moves a buckle, with which a tongue that has a webbing inserted therein engages, between a normal position and a raised position that is further toward a seat upper side than the normal position; a retractor that includes: a spool and a lock mechanism that locks rotation of the spool in the pull-out direction, and that releases the locked state by causing rotation of the spool in the take-up direction; and a controller that, due to a signal from a collision prediction sensor that predicts a collision of a vehicle, causes rotation of the spool in the take-up direction and increases tension acting on the webbing, and actuates the buckle moving mechanism to move the buckle from the normal position toward the raised position in a case in which the vehicle collision has been avoided.

Abstract: An occupant protection device includes: a lumbar support section that is displaceable between an upper limit position and a lower limit position, and is displaceable between an advanced position pressing against the lumbar region and a retreated position further to a seatback rear side than the advanced position; a displacement mechanism that displaces a frontmost location of the lumbar support section; a rear collision prediction section that predicts a rear-end collision to a vehicle; and an actuation controller that, in cases in which a vehicle rear-end collision has been predicted by the rear collision prediction section in a state in which the frontmost location of the lumbar support section is not at the lower limit position, controls the displacement mechanism, and sets the frontmost location at the lower limit position and at the advanced position.
