Abstract: Disclosed is a seat including: sensors which includes a first cushion sensor provided at a seat cushion in a position corresponding to buttocks of an occupant, a second cushion sensor provided at the seat cushion and located farther frontward than the first cushion sensor, a first back sensor provided at a seat back and located in a lower position thereof, and a second back sensor provided at the seat back and located above the first back sensor; and a controller connected to the sensors and thereby allowed to acquire pressure values from the respective sensors. The controller is configured to identify the motion of the occupant based on outputs of at least two sensors of the first cushion sensor, the second cushion sensor, the first back sensor, and the second back sensor.

Abstract: A seat includes a seat body and a sensor configured to acquired information on an occupant seated on the seat body. The seat includes a coating as a location marker that marks a location of the sensor to render the location visually recognizable from outside the seat body.

Abstract: A lower vehicle-body structure of a vehicle may include: a floor panel; a side sill; and a frame member that extends in the front-rear direction on the vehicle-width-direction inner side of the side sill and includes a front-rear extended portion that is in abutment against the side sill on the vehicle-width-direction inner side and extends in the vehicle front-rear direction along the side sill. The front-rear extended portion may include: a bottom face portion; an inner wall portion; and an inner-side flange that extends to the vehicle-width-direction inner side from a distal end portion of the inner wall portion and is joined to the floor panel. Deformation facilitating facilitators that facilitate deformation of the bottom face portion in the vehicle width direction when a collision load in the vehicle width direction is input may be formed in the bottom face portion.

Abstract: A floor tunnel protruding upwardly and extending in a vehicle longitudinal direction at a central position, in a vehicle width direction, of a floor panel, a cross member having ridgelines extending in the vehicle width direction at a rear end of the floor tunnel and a closed-cross section portion interconnecting a pair of right-and-left side sills, and a pair of right-and-left battery units positioned below the floor panel and between the side sills and provided on right-and-left sides, in the vehicle width direction, of the floor tunnel are provided. The cross member is provided with a reinforcement portion to reinforce the ridgelines in a range, in the vehicle width direction, which includes at least the position of the battery units and excludes the central position, in the vehicle width direction, of the floor panel.
