The vehicle 30 includes a table 36 in the passenger compartment 34, a circular track 38 fixed in the compartment 34 and extending around the table 36, and a plurality of seats 40 mounted to and independently slidable along the track 38.

(10) The vehicle 30 provides a versatile passenger compartment 34 that may be used, e.g., when the vehicle 30 is autonomously operated. The table 36 provides an area for occupants to collaboratively work or play. The passenger compartment 34 provides a spacious interior space for occupants to use. Occupants may increase free space by moving and/or stowing the seats 40, as discussed further below. In some configurations, the passenger compartment 34 may open to the external environment, providing a variety of surroundings for occupants.

(11) The vehicle 30 may be an autonomous vehicle. A vehicle controller (not shown), sometimes referred to as the virtual driver, may be capable of operating the vehicle 30 independently of the intervention of a human driver, to a greater or a lesser degree. The vehicle controller may be programmed to operate an engine, braking system, steering, and/or other vehicle systems.

(12) With reference to FIGS. 1-3 and 7-8, the vehicle 30 includes a frame 42. The frame 42 may be of a unibody construction, a body-on-frame construction, or of any other suitable construction. The frame 42 may be formed of any suitable material, for example, steel, aluminum, etc. The frame 42 may include a front end 44 housing an engine (not shown) and a base 46 supporting the passenger compartment 34.

(13) The vehicle 30 includes a passenger compartment 34 to house occupants, if any, of the vehicle 30. The passenger compartment 34 is enclosed by the wall 32, a roof 48, and a floor 50. The passenger compartment 34 may be supported by the base 46.

(14) The base 46 is part of the frame 42. The base 46 may support the passenger compartment 34. Specifically, the base 46 may support the floor 50, and the base 46 may support the wall 32.

(15) The floor 50 is supported on the frame 42, specifically on the base 46. The floor 50 may support the wall 32, the table 36, and the seats 40. The floor 50 may be rotatable relative to the frame 42. For example, the floor 50 may rotate on the base 46. Rotation of the floor 50 may be powered by, e.g., an electric motor. The base 46 and/or the floor 50 may include tracks (not shown) for guiding rotation of the floor 50 relative to the base 46. Rotating the floor 50 may correspondingly rotate the seats 40, the table 36, the wall 32, and/or the roof 48 relative to the frame 42. For example, the floor 50, the table 36, and the seats 40 may all rotate together relative to and within the wall 32 and the roof 48. For another example, the floor 50 and the seats 40 may rotate together relative to and about the table 36. For a third example, the floor 50, the table 36, the seats 40, the wall 32, and the roof 48 may all rotate together relative to the frame 42 and the front end 44.

(16) The wall 32 may be supported by the base 46 and/or the floor 50. The wall 32 has a cylindrical shape and surrounds the passenger compartment 34. The wall 32 may support the roof 48. The wall 32 may have gaps 52 for one or more doors 54, as shown in FIG. 3.

(17) With reference to FIGS. 7-8, the wall 32 may include a plurality of wall segments 56 arranged circumferentially about the passenger compartment 34. The wall segments 56 may be rotatable radially outward relative to the base 46, as shown in FIG. 8. The wall segments 56 may fold down away from the passenger compartment 34. The wall segments 56 may be movable from an upright position adjoining each other, as shown in FIG. 7, to an unfolded position extending radially away from the base 46, as shown in FIG. 8. The wall segments 56 may be movable together or independently. The wall segments 56 may include any suitable interlocking features, seals, etc. (not shown), for interlocking to each other in the upright position. One or more of the wall segments 56 may include one or more entries (not shown), e.g., doors 54, allowing ingress and egress to the passenger compartment 34 when the wall segments 56 are in the upright position.

(18) Between each pair of wall segments 56 is a support beam 78. The support beams are components of the frame 42. The support beams 78 may provide support for the roof 48 and may provide structural rigidity for the vehicle 30. When the wall segments 56 are in the upright position, as shown in FIG. 7, the wall segments 56 may cover the support beams 78 or may reveal the support beams 78.

(19) With reference to FIGS. 1-3 and 7-8, the roof 48 may be supported by the wall 32. The roof 48 may have a dome shape, i.e., rounded such as a partial sphere, a truncated partial sphere, etc. The roof 48 may extend over the table 36 and the plurality of seats 40. The roof 48 may be transparent. For example, the roof 48 may be formed of glass.

(20) With reference to FIGS. 7-8, the roof 48 may include a lower roof portion 80 and an upper roof portion 82. The lower roof portion 80 may be supported by the support beams 78. The upper roof portion 82 may be located concentrically in a center of the lower roof portion 80. The upper roof portion 82 may include a plurality of roof segments 58. The roof segments 58 may each be shaped like a circle sector, that is, pie shaped. Some of the roof segments 58 may open and close by rotating about a center of the roof 48 underneath or above other roof segments 58, as shown in FIG. 8.

(21) With reference to FIGS. 1-3, the wall 32 may include one or more doors 54. The door 54 may have a curved shape corresponding to the cylindrical shape of the wall 32. The door 54 may be slidable along an exterior of the wall 32, as identified with an arrow in FIGS. 1-3. The door 54 may be circumferentially movable between a closed position covering a gap 52 in the wall 32, as shown in FIGS. 1 and 2, and an open position revealing the gap 52 in the wall 32, as shown in FIG. 3. Alternatively, the door 54 may open in another manner such as sliding upward, swinging outward about a vertical axis, swinging downward about a horizontal axis to form a ramp, etc. The door 54 and/or the wall 32 may include any suitable track, guiding system, etc., for guiding movement of the door 54 relative to the wall 32 between the open position and the closed position.

(22) With reference to FIGS. 2,3, and 8, the table 36 may be disposed in the passenger compartment 34. The table 36 may be circular and may be centered within the passenger compartment 34. In other words, the table 36 may form a concentric circle with the wall 32. The table 36 may be sized so that an occupant in any of the seats 40 can reach and use a tabletop 60 of the table 36. The table 36 may be retractable toward the floor 50 in order to provide more space to occupants. The table 36 may be movable from a raised position in which the tabletop 60 is spaced from the floor 50 to a lowered position in which the tabletop 60 touches the floor 50.

(23) An airbag 62 may be supported by the table 36. Specifically, the airbag 62 may be stored at a center of the table 36. The airbag 62 may be inflatable from an undeployed state to a deployed state. The airbag 62 in the undeployed state is stored within the table 36 or under the tabletop 60 of the table 36. The airbag 62 in the deployed state extends upward from the tabletop 60. The airbag 62 in the deployed state may extend radially outward from the table 36 toward occupants, if any.

(24) The airbag 62 may be formed of any suitable airbag material, for example, a woven polymer. For example, the airbag 62 may be formed of woven nylon yarn, for example, nylon 6-6. Other suitable examples include polyether ether ketone (PEEK), polyetherketoneketone (PEKK), polyester, or any other suitable polymer. The woven polymer may include a coating, such as silicone, neoprene, urethane, and so on. For example, the coating may be polyorgano siloxane.

(25) With reference to FIGS. 2-6 and 8, as one example, the circular track 38 may be fixed in the passenger compartment 34 and may extend around the table 36. The floor 50 may support the track 38, as shown in FIGS. 4 and 5. The track 38 may be recessed into the floor 50, as shown in FIGS. 4 and 5, or the track 38 may extend upward from the floor 50. The track 38 may form a concentric circle with the wall 32 and/or with the table 36.

(26) As another example, the track 38 may be supported on the wall 32, as shown in FIG. 6. The track 38 may include a wall track segment 74 and a door track segment 64. The wall 32 may support the wall track segment 74 and the door 54 may support the door track segment 64. When the door 54 is in the closed position, the door track segment 64 may align with the wall track segment 74, and any gap between the wall track segment 74 and the door track segment 64 may be short enough that the seats 40 may slide over the gap between the track 38 and the door track segment 64.

(27) With reference to FIGS. 4-6, the plurality of seats 40 may be mounted to and independently slidable along the track 38. If the track 38 is supported on the wall 32, each seat 40 may be slidable along the track 38 onto and off of the door track segment 64. Each seat 40 may be adjacent the wall 32, that is, nothing is positioned between each seat 40 and the wall 32. Each seat 40 may include a pedestal 66, a seatback 68, and a seat bottom 70.

(28) Each seat 40 includes the pedestal 66. The pedestal 66 is mounted to and slidable along the track 38. The pedestal 66 may include a head 76 slidably engaged with the track 38. The head 76 and the track 38 may have any shape and, for example, may be corresponding shapes, to encourage slidable engagement between the pedestal 66 and the track 38. The pedestal 66 may extend from the track 38 to the seat bottom 70 or to a hinge 72 between the seat bottom 70 and the seatback 68. The seat 40 is rotatable about the pedestal 66.

(29) Each seat 40 has the seatback 68. The seatback 68 may provide support for a back of an occupant seated in the seat 40. The seatback 68 may extend generally vertical relative to the passenger compartment 34; for example, the seatback 68 may recline approximately 17? from vertical relative to the passenger compartment 34.

(30) Each seat 40 has the seat bottom 70. The seat bottom 70 is rotatable relative to the seatback 68 between a sitting position and an upright position. In the sitting position, as shown in FIGS. 4 and 6, the seat bottom 70 is generally horizontal relative to the passenger compartment 34. In the upright position, as shown in FIG. 5, the seat bottom 70 is generally vertical relative to the passenger compartment 34. The seat bottom 70 may be rotatable relative to the hinge 72. The hinge 72 may include a spring (not shown) biasing the seat bottom 70 to the upright position.

(31) With reference to FIGS. 7-8, in the configuration in which the wall 32 includes the wall segments 56 and the roof 48 includes the lower and upper roof portions 80, 82, then the passenger compartment 34 may be transformable between a closed state and an open state. In the closed state, shown in FIG. 7, the wall segments 56 adjoin each other in the upright position to form the wall 32 in a cylinder shape, and the roof segments 58 are arranged to close the upper roof portion 82. In the open state, as shown in FIG. 8, the wall segments 56 are splayed radially outward from the passenger compartment 34 in the unfolded position, and the roof segments 58 may be arranged to open one or more sections of the upper roof portion 82. To transition the passenger compartment 34 from the closed state to the open state, the wall segments 56 may rotate radially outward and downward relative to the base 46, and the roof segments 58 may rotate about the center of the upper roof portion 82. To transition the passenger compartment 34 from the open state to the closed state, the wall segments 56 may rotate radially inward until the wall segments 56 adjoin each other, and the roof segments 58 rotate in an opposite direction about the center of the upper roof portion 82.
