FIELD
The present invention relates to a seat configuration for a vehicle. The present invention also relates to a seating system for a vehicle such as an autonomous vehicle. The present invention also further relates to a vehicle interior component such as a vehicle seat. The present invention further relates to a seat assembly comprising a base assembly and a seat structure.
BACKGROUND
It is well known to provide a set of seats for occupants of a vehicle. It is also well known to provide a seat for a vehicle that comprises a seat base and a backrest. It is also known to provide a seat for a vehicle in which the seat base is installed to the vehicle interior on a set of floor tracks and at least partially adjustable in the set of floor tracks along a linear path. It is also known to provide a seat for a vehicle in which the seat base is at least partially adjustable along the set of floor tracks and the backrest is pivotally attached to the seat base and at least partially adjustable by pivotal movement relative to the seat base.
Such a conventional seat for a vehicle providing for sliding adjustment of the position of the seat base and for pivotal adjustment of the backrest relative to the seat base may be configured to provide for adjustments in a range generally to facilitate a range of size of vehicle occupants (such as a driver). In such a conventional seat for a vehicle, the adjustments are provided by separate mechanisms (e.g. a mechanism for sliding adjustment located under or at the seat base and a mechanism for pivotal adjustment of the backrest located at the back of the seat base and bottom of the backrest); in such a conventional seat arrangement the available adjustments are generally restricted to a linear direction for seat position adjustment (e.g. seat base movement constrained on the set of tracks) and pivotally for the backrest (e.g. constrained at the pivot point attaching the backrest to the seat base); in such a conventional seat arrangement the degree of comfort that may be provided to a vehicle occupant in the seat may be restricted by the constraints on available movement of the seat.
It would be advantageous to provide for a seat configuration for a vehicle interior providing for a plurality of available movements of the seat relative to the vehicle interior. It would also be advantageous to provide for a seat system that can be adjusted and configured for vehicle occupant use and comfort. It would further be advantageous to provide for a seat arrangement for a vehicle interior providing for a plurality of available movements including at least two movements such as recline movement and rotation/swivel movement and/or tilt/roll movement. It would further be advantageous to provide a seat assembly for a vehicle interior comprising an improved seat structure providing at least two movements for the seat to be mounted on an improved base arrangement providing a compact form. It would further be advantageous to provide a seat assembly for a vehicle interior comprising a seat movable in multiple directions relative to a base that is provided in a compact form. It would further be advantageous to provide a seat assembly that has a removable seat structure.
It would be advantageous to provide a seating system that provides at least one of the identified advantageous features or other features of potential benefit or use for a vehicle interior.

According to an exemplary embodiment, vehicle V may comprise an adjustable seat arrangement; as indicated the seat arrangement may comprise seats in a configuration in a vehicle interior with features that are complementary and useful for a wide variety of types of vehicles (and/or that are capable of implementation in a manner useful/unique to autonomous vehicles).
According to an exemplary embodiment, the seats (e.g. one seat or each seat including the driver seat) in the vehicle interior may be detached, attached, re-oriented, adjusted in use by occupants, etc. See FIGS. 1A and 1B. See also FIGS. 3A-3D, 4A-4L and 5A-5L. As indicated schematically in the FIGURES, according to an exemplary embodiment a vehicle seat may be provided with multiple types of adjustability (e.g. rotate, tilt, translate, roll, swivel, shift, lift/lower, etc. as to give a wide variety of positions/positioning such as may be felt by a passenger-occupant as “floating” in the interior of the vehicle). As indicated according to an exemplary embodiment, the vehicle seat may be combined with various other known/conventional seat control/comfort systems (e.g. automated adjustment mechanisms, slide at base/relative to vehicle floor, raise/lower height, relative to vehicle floor, tilt/recline, heating/cooling, etc.).
According to an exemplary embodiment as shown schematically in FIGS. 1A-1C, in a vehicle such as an autonomous (autonomously driven) vehicle it may be appropriate (at times where permitted/proper) to re-orient the seating arrangement (e.g. position and orientation of vehicle seats) including in proper circumstances the so-called “driver seat”; in an autonomous vehicle the mode of operating the vehicle may permit various movements and positioning and orientation/re-orientation of one seat and/or multiple seats to facilitate purposes such as occupant interaction/activity and comfort/rest as well as driver attention/comfort, etc.
According to an exemplary embodiment, a seat for vehicle interior is intended to be attached to a seat support shown as a shell. See FIGS. 1B-1C and D-1E (showing entire seat assembly with seat/seat structure on seat support and installed on base assembly as in use/operation in vehicle).
According to an exemplary embodiment as shown schematically, seat support 100 is attached to base assembly 200 at a slot or track 130s to form seat system 300; slot 130s is configured to facilitate movement of seat support 100 in the fore/aft direction and rotation of seat support 100 about fastener 210. See FIGS. 3A-3D.
According to an exemplary embodiment as shown schematically, seat support 100 is configured to slide along slot or track 130s to facilitate movement of seat support 100 in the fore/aft direction (e.g. recline movement). See FIGS. 4A-4C and 5A-5C.
According to an exemplary embodiment as shown schematically, seat support 100 is configured to rotate around fastener 210 to facilitate swivel of seat support 100 (e.g. swivel/rotation movement). See FIGS. 4D-4F and 5D-5F.
According to an exemplary embodiment as shown schematically, seat support 100 is configured to roll/slide along slot or track 230s to facilitate side to side movement of seat support 100 (e.g. roll/tilt movement). See FIGS. 4G-4I and 5G-5I, 6A and 6C.
As shown schematically in FIGS. 4J-4L, seat support 100 can be detached from base assembly 200 by sliding seat support 100 rearward. See also FIGS. 5J-5L. As shown schematically in FIGS. 4J to 4L according to an exemplary embodiment, seat support 100 can be detached from base assembly 200 by sliding seat support 100 rearward.
As shown schematically in FIGS. 4J-4L, seat support 100 can be detached from base assembly 200 by sliding seat support 100 rearward.
As shown schematically in FIGS. 3B-3D, fastener 210 and mounting plate 240 are configured to secure plate 220 onto base 230 and facilitate side to side movement of plate 220 along track 230s. See also FIGS. 6A-6F.
As shown schematically in FIGS. 3B and 6B, feature 222 is generally diamond shaped (i.e. rhombus). One of the diagonal of feature 222 corresponds to the width of the inner section of slot/track 130s; feature 222 is intended to provide stability and define the range of swivel of seat support 100 relative to base assembly 200.
As shown schematically in FIGS. 3B, 7B-7C and 8A-8D, fastener 210 provides a portion shown as a cap and a portion shown as a post providing thread. The diameter of the cap generally corresponds to the width of the outer section of track 130s. Cap is intended to provide stability for seat support 100.
As shown schematically according to an exemplary embodiment in FIGS. 1B-1E, seat support 100 may be attached to base assembly 200 to form seat system 300.
As shown schematically in FIGS. 3A-3D and 8A-8D, seat support 100 may be attached to base assembly 200 via slot/track 130s.
As shown schematically in FIG. 8C, tabs 120 are intended be retractable; tabs 120 are configured to be at a retracted position to allow the cap of fastener 210 to enter/exit the slot or track 130s.
As shown schematically in FIG. 8D, tabs 120 are configured to be at an extended position to retain the cap of fastener 210.
