Abstract

A vehicle is disclosed with a seating assembly which is capable of prompting an occupant to take an appropriate riding posture depending on the behavior of the vehicle body. A motorcycle includes tilting mechanisms for tilting seating surfaces of a front seat (rider seating part) and a rear seat (passenger seating part) and an ECU carries out a control process for tilting the seating surfaces to lift rear portions of the seats upwardly in response to an action to accelerate the motorcycle and a control process for tilting the seating surfaces to lift front portions of the seats upwardly in response to an action to decelerate the motorcycle.

First claim

The invention claimed is:

1. A vehicle including a seating assembly for an occupant to be seated thereon and a tilting mechanism tilting said seating assembly, the vehicle comprising:
a controller configured to control said tilting mechanism, and
wherein said tilting mechanism serves as a mechanism for tilting a seating surface of said seating assembly, and said controller carries out a first control process for tilting said seating surface such that said seating assembly has a rear portion lifted upwardly on a basis of acceleration of said vehicle and a second control process for tilting said seating surface such that said seating assembly has a front portion lifted upwardly on a basis of deceleration of said vehicle, and
wherein said controller decides that the vehicle is ready to start when a clutch of the vehicle cuts off power transmission and a transmission of the vehicle is in other than a neutral position when a vehicle speed of the vehicle is zero, and carries out the first control process for tilting said seating surface such that said seating assembly has the rear portion lifted upwardly when said controller decides that the vehicle is ready to start, and carries out a third control process for returning said seating surface into a position in which said seating surface lies flatwise horizontally when said controller decides that the vehicle is not ready to start.

2. The vehicle including the seating assembly, according to claim 1 , wherein said controller carries out the first control process for tilting said seating surface such that said seating assembly has the rear portion lifted upwardly when the vehicle is having a positive acceleration equal to or greater than a predetermined value when the vehicle speed of the vehicle is other than zero, carries out the second control process for tilting said seating surface such that said seating assembly has the front portion lifted upwardly when the vehicle is having a negative acceleration smaller than the predetermined value, and carries out the third control process for returning said seating surface into a position in which said seating surface lies flatwise horizontally when the acceleration of the vehicle falls within a predetermined range.

3. The vehicle including the seating assembly, according to claim 1 , wherein an angle of said seating surface of said seating assembly is changed depending on the acceleration of the vehicle in the first control process for tilting said seating surface.

4. The vehicle including the seating assembly, according to claim 1 , wherein said tilting mechanism includes
a base supported on a frame of the vehicle,
a seat tiltably mounted on said base, and
an actuator tilting said seat.

5. The vehicle including the seating assembly, according to claim 4 , wherein said seat is mounted on said base for vertical swinging movement about a swing shaft, and an end of a link arm is coupled to a portion of said seat which is spaced from said swing shaft, and said seat is tilted when another end of said link arm is moved by said actuator.

6. The vehicle including the seating assembly, according to claim 4 , further comprising:
a roller mounted on either one of said base and said seat; and
a rail mounted on the other one of said base and said seat and having a slanted surface for tilting said seat in response to rolling movement of said roller,
wherein said actuator moves said seat to cause said roller to roll on said slanted surface of said rail.

7. The vehicle including the seating assembly, according to claim 6 , wherein said roller includes a plurality of rollers spaced laterally on a front lower portion of said seat and a plurality of rollers spaced laterally on a rear lower portion of said seat.

8. The vehicle including the seating assembly, according to claim 4 , wherein said actuator includes expandable bodies disposed forwardly and rearwardly of a swing shaft and a fluid pump expanding or contracting said expandable bodies to tilt said seat.

9. The vehicle including seating assembly, according to claim 4 , wherein said seat includes seats disposed in front and rear portions of said seating assembly.

10. The vehicle including the seating assembly, according to claim 1 , wherein said tilting mechanism includes a plurality of seats tiltably mounted on a frame member of said seating assembly and tilting each of front and rear portions of said seating surface, and an actuator tilting each of said seats.
