Description
FIELD

The present disclosure relates to a stowable seat for a vehicle.

BACKGROUND

Automotive vehicles include seat assemblies for supporting occupants within a cabin of the vehicle. Some seat assemblies are able to be removed from the vehicle by a user or moved by the user between a seating position and a stowed position to tradeoff passenger seating space for additional cargo space within the cabin of the vehicle. Removing seat assemblies from a vehicle can be cumbersome and storage of a removed seat assembly can be troublesome. Stowable seat assemblies provide the convenience of being able to quickly and easily switch between additional seating space and additional cargo space within the cabin of the vehicle without the heavy lifting or storage hassles associated with removable seat assemblies.

 DETAILED DESCRIPTION

In an exemplary embodiment and with reference to FIGS. 1 and 2, a vehicle 10 is provided that may include a source of rotary power 12 (e.g., an engine and/or an electric motor), a drivetrain 14, and a body 16. The drivetrain 14 may be a rear-wheel-drive, four-wheel-drive or all-wheel-drive system, for example, and may include a transmission 20, a propshaft 22 and a rear axle assembly 24. The transmission 20 may be operatively connected to the source or rotary power 12. The propshaft 22 may be operatively connected with the transmission 20 and may transmit rotary power from the source or rotary power 12 to the rear axle assembly 24. As will be subsequently described, a rear, center seat assembly 52 of the vehicle 10 may be movable within the body 16 between a seating position (shown in solid lines in FIG. 2) and a stowed position (shown in phantom lines in FIG. 2). The rear, center seat assembly 52 may be stowed in a position that avoid the propshaft 22 and occupies little or no space within an occupant cabin 30 of the vehicle 10. It will be appreciated, however, that the principles of the present disclosure are also applicable to front-wheel-drive vehicles (i.e., vehicles that do not include a propshaft disposed below a rear, center seat assembly).

The body 16 of the vehicle 10 may include a front-end compartment 26, a cargo bed 28, and the occupant cabin 30. The front-end compartment 26 may house the source of rotary power 18. The cargo bed 28 may be an open compartment disposed in a rear portion of the vehicle 10 and may include a floor 32, a back wall 34, a pair of side walls 36 and a tailgate 38.

The occupant cabin 30 may be a space bounded by a front-end panel 40, a ceiling panel 42, a floor panel 44 and a back-wall panel 46. The occupant cabin 30 may include one or more front seat assemblies 48 (FIG. 2), a pair of rear, laterally outboard seat assemblies 50 (FIG. 1), and the rear, center seat assembly 52. The rear, laterally outboard seat assemblies 50 may be disposed on either side of the rear, center seat assembly 52 and may cooperate with the rear, center seat assembly 52 to form a row of seats. The rear, laterally outboard seat assemblies 50 may be individually movable between seating positions and stowed positions in which each rear, laterally outboard seat assembly 50 may be received in respective compartments 54 disposed beneath the floor panel 44 and on either side of the propshaft 22. The rear, laterally outboard seat assemblies 50 may be Stow 'n Go® seats (by Chrysler Group LLC) or the rear, laterally outboard seat assemblies 50 may be of the type disclosed in Assignee's commonly owned U.S. Pat. No. 7,377,571, for example, the disclosure of which is hereby incorporated by reference herein. It will be appreciated that the rear, laterally outboard seat assemblies 50 may include any other suitable mechanism for stowing the rear, laterally outboard seat assemblies 50 in the compartments 54.

Referring now to FIGS. 2-7, the rear, center seat assembly 52 may be stowable between a seating position (shown in FIG. 4 and in solid lines in FIG. 2) and a stowed position (shown in FIGS. 6 and 7 and in phantom lines in FIG. 2). The rear, center seat assembly 52 may be at least partially received in a space 56 (shown in FIGS. 2 and 4-6) defined by the vehicle body 16 that is disposed outside of the occupant cabin 30 (e.g., rearward of the rear boundary of the occupant cabin 30) when the rear, center seat assembly 52 is in the stowed position.

The space 56 may be a generally L-shaped space including a vertical portion 58 and a horizontal portion 60. The vertical portion 58 may be disposed between the back-wall panel 46 of the occupant cabin 30 and the back wall 34 of the cargo bed 28 and may include a rear face 61 and an opening 62 in communication with the occupant cabin 30. The horizontal portion 60 may include an open end 64, a closed end 66, a bottom surface 68 and a top surface 70. The open end 64 may be in communication with the occupant cabin 30 and may be generally aligned with the opening 62 of the vertical portion 58. The bottom surface 68 may be disposed above the propshaft 22 and may be substantially coplanar with the floor panel 44 of the occupant cabin 30 or slightly above or below the floor panel 44. The bottom and top surfaces 68, 70 may be disposed below the floor 32 of the cargo bed 28.

The rear, center seat assembly 52 may be disposed above the propshaft 22 (i.e., the propshaft 22 is disposed below the floor panel 44 and the rear, center seat assembly 52). The rear, center seat assembly 52 may include a seat bottom 72 and a seatback 74. The seat bottom 72 may include a seat bottom frame 76 and a seat cushion 78. The seat bottom frame 76 may include a first base plate 80, a pair of first links 82, a pair of second links 84, a pair of arms 86, and a second base plate 88. The arms 86 may extend upward from sides of the first base plate 80 and may selectively pivotably engage the seatback 74. The first and second links 82, 84 may be pivotably connected to the first base plate 80 and pivotably connected to the floor panel 44 of the occupant cabin 30. In this manner, the first and second links 82, 84, the first base plate 80 and the floor panel 44 cooperate to form a linkage that moves the seat bottom 72 between a raised position in which the seat cushion 78 is spaced apart from the floor panel 44 (shown in FIG. 4) and a lowered position in which the seat cushion 78 may be generally aligned with the horizontal portion 60 of the space 56 (shown in FIG. 5). When the seat bottom 72 is in the lowered position, the first and second links 82, 84 may be received in slots in the floor panel 44 so that the first and second links 82, 84 may be generally flush with the floor panel 44.

The second base plate 88 may be fixedly attached to the seat cushion 78 and may be slidably attached to the first base plate 80. The second base plate 88 may be slidable relative to the first base plate 80 between a forward position (shown in FIGS. 3-5) and a rearward position (shown in FIGS. 6 and 7). The second base plate 88 may include slots 90 that may receive corresponding cleats 92 that extend upward from the first base plate 80. Engagement between the cleats 92 and the slots 90 may limit an amount of forward travel of the second base plate 88 (and hence the seat cushion 78) relative to the first base plate 80. When the cleats 92 are fully received within the slots (i.e., when the second base plate 88 is in the forward position shown in FIG. 3), friction between the cleats 92 and detents in the slots 90 may restrict the second base plate 88 and seat cushion 78 from sliding rearward relative to the first base plate 80 until a predetermined minimum amount of force is applied to the seat cushion 78 to release the engagement between the cleats 92 and slots 90. It will be appreciated that additional or alternative locking mechanisms could be employed to releasably secure the second base plate 88 relative to the first base plate 80 until relative movement therebetween is desired.

The seatback 74 may include a back-support cushion 94 and a seatback frame 96. A handle 97 may extend outward from the back-support cushion 94 and may be grasped by a user when moving the rear, center seat assembly 52 from the stowed position (FIGS. 6 and 7) to the seating position (FIGS. 3 and 4). The seatback frame 96 may include a lower end 98 and an upper end 100. The lower end 98 may be engaged with the arms 86 of the seat bottom frame 76. The lower end 98 may be selectively rotatable relative to the arms 86. A locking mechanism 102 (shown schematically in FIGS. 3-6) may lock the lower end 98 relative to the arms 86 to prevent relative rotation therebetween when the rear, center seat assembly 52 is in the seating position (FIGS. 3 and 4). The locking mechanism 102 may be selectively unlocked to allow relative rotation between the seatback 74 and the seat bottom frame 76, thereby allowing rotation of the first and second links 82, 84 toward the lowered position shown in FIG. 5. It will be appreciated that the locking mechanism 102 could be any suitable type of locking mechanism to selectively allow and prevent relative rotation between the seat bottom 72 and the seatback 74. For example, the locking mechanism 102 could be similar to a locking mechanism commonly employed in seat dumping or reclining mechanisms.

The upper end 100 of the seatback frame 96 may be pivotably connected to a pair of third links 104 that may be pivotably connected to the rear face 61 of the vertical portion 58 of the space 56. The seatback 74 may also include a headrest 106 that may be slidable up and down relative to the seatback frame 96.

With reference to FIGS. 4-7, operation of the rear, center seat assembly 52 will be described in detail. As described above, the rear, center seat assembly 52 may be movable between a seating position (shown in FIG. 4) and a stowed position (shown in FIGS. 6 and 7) without disengaging the rear, center seat assembly 52 from the vehicle body 16. In the stowed position, the rear, center seat assembly 52 does not encroach on a space occupied by the propshaft 22 in a conventional vehicle and occupies little or no space within the occupant cabin 30 of the vehicle 10.

To move the rear, center seat assembly 52 from the seating position to the stowed position, a user may first unlock the locking mechanism 102 to allow the seatback 74 to rotate relative to the seat bottom frame 76. Once the locking mechanism 102 is unlocked, the first, second and third links 82, 84, 104 are able to be rotated toward the positions shown in FIG. 5. That is, the seatback 74 can be moved into the vertical portion 58 of the space 56 and the seat cushion 78 can be moved into the lowered position in which the seat cushion 78 may be generally aligned with the horizontal portion 60 of the space 56 (as shown in FIG. 5). Next, the seat cushion 78 can be slid relative to the seat bottom frame 76 into the horizontal portion 60 of the space 56, as shown in FIGS. 6 and 7.

To move the rear, center seat assembly 52 from the stowed position to the seating position, the user may reverse the steps described above. First, the user may pull the seat cushion 78 out of the horizontal portion 60 of the space 56 toward the front end of the vehicle 10 until the cleats 92 are fully received in the slots 90 in the second base plate 88 (i.e., in the position shown in FIG. 5). While not shown in the figures, a handle could be formed on the seat cushion 78 that the user may grasp and pull on to slide the seat cushion 78 out of the horizontal portion 60 of the space 56.

Next, the user may grasp and pull on the handle 97 of the seatback 74 (or grasp and pull on any other structure of the rear, center seat assembly 52) to rotate the first, second and third links 82, 84, 104 from the position shown in FIG. 5 to the seating position shown in FIG. 4. Upon reaching the seating position, the locking mechanism 102 may lock the seatback 74 relative to the arms 86 to lock the rear, center seat assembly 52 in the seating position. Once the rear, center seat assembly 52 is in the seating position, the position of the headrest 106 can be adjusted as desired to suit a particular passenger of the vehicle 10.

While the rear, laterally outboard seat assemblies 50 are described above as being stowable in the compartments 54 below the floor panel 44, in some embodiments, the space 56 may be laterally wide enough to receive the rear, laterally outboard seat assemblies 50 in addition to the rear, center seat assembly 52. In such embodiments, the structure of the rear, laterally outboard seat assemblies 50 may be similar to that of the rear, center seat assembly 52 described above to facilitate movement into and out of the space 56. Furthermore, in some embodiments, the rear, laterally outboard seat assemblies 50 and the rear, center seat assembly 52 may be combined into a single, integrated seat assembly that is movable, as a whole, into and out of the space 56.
