The technology described in the present specification is embodied in a vehicle. The vehicle includes a vehicle body, a seat, and a seat bracket. The vehicle body includes a pipe material extending in the vehicle right-left direction. The seat is provided in the vehicle body, and an occupant of the vehicle sits on the seat. The seat is fixed to the pipe material via the seat bracket. The seat bracket includes a bracket lower and a bracket upper. The bracket lower is placed below the pipe material. The bracket upper is placed above the pipe material such that the pipe material is sandwiched between the bracket upper and the bracket lower.

An embodiment vehicle includes a detector configured to obtain information on whether a rear occupant is present in a rear seat and a state of the rear occupant, an audio, video, navigation, telematics terminal (AVNT) device configured to output the information on the state of the rear occupant, and a controller configured to, in response to detecting that the rear occupant is present in the rear seat, control the detector to obtain the information on the state of the rear occupant in real time and control the AVNT device to allow a user interface to be output, wherein the user interface is based on a position of the rear occupant and the information on the state of the rear occupant.

A noise canceling adaptive filter outputs, from a front seat speaker, a noise canceling sound generated by applying a transfer function X(z) adapted by an adaptive operation using an output of a front seat microphone as an error to an output sound of a sound source apparatus. An output of the front seat microphone is added to an output of an audio feedback canceling filter by a second adder, added to an output sound of the sound source apparatus by a third adder, and output from a rear seat speaker. The audio feedback canceling filter applies a transfer function X′(z) and a transfer function C^(z) on an output of the second adder and outputs a resultant. The transfer function C^(z) corresponds to a transfer function C(z) from the front seat speaker to the front seat microphone. In synchronization control, the transfer function X(z) is set as the transfer function X′(z).

A removable seat assembly for a vehicle, including a base assembly having a riser portion configured to support a seat; a frame structure coupled to and supporting the riser portion, the frame structure defining a first generally planar surface configured to support a floor section; a seat dolly coupled to the frame structure, the seat dolly including a plurality of wheels for moving the seat assembly from a first position to a second position; a floor base assembly defining a substantially planar surface for receiving the plurality of wheels of the seat dolly as the seat assembly is moved from the first position to the second position; and a mounting bracket configured to releasably lock the seat dolly to the floor base assembly.

The vehicle body structure includes a front floor panel, a rear floor panel positioned lower than the front floor panel, and a connection panel extending from a rear portion of the front floor panel to a front portion of the rear floor panel and inclined or curved so as to be positioned downward toward a rear side. At least the front portion of the connection panel is positioned at the front of the front portion of the front seat.

An embodiment vehicle driver's seat structure includes a dashboard floor panel combined with a front of a center floor panel and having a shape extending in an upward inclined direction, a lower seat support installed on a top surface of the center floor panel and extending along a vehicle front-rear direction, an upper seat support installed on top of the lower seat support and underneath a driver's seat to support the driver's seat, and an upper floor horizontally connecting the upper seat support and the dashboard floor panel to each other.

A vehicle seat (10) has a seat cushion (20) and a seat back (30), which are affixed to the body of a vehicle. The seat back (30) has: a first member (50) which is formed in a plate-like shape; and a second member (60) with a hat-shaped cross-section, which is configured so that a flange section (61) is in contact with one surface, in a thickness direction, of the first member (50). A center bead (52) is provided at the center portion of the first member (50). The center bead (52) is configured so that a longitudinal end of the center bead (52) and the second member (60) are overlapped in a plan view viewed in the thickness direction of the first member (50). As a result, the first member (50) of the seat back (30) is prevented from being deformed at the longitudinal end of the center bead (52).
