Description

Technical Field

[0001] The present invention relates to a vehicle seat used in a vehicle having a plurality of rows of seats, and a vehicle equipped with the vehicle seat.

Background Art

[0002] Generally, in a vehicle equipped with a three-row seat, the driver's seat and the front passenger seat in the front row are each provided with a door for getting on and off, and for the seats behind, there are many designs with one door for getting on and off on both the left and right sides, or on either the left or right side. In this case, it is common to provide a mechanism for moving the middle row seat forward to facilitate access to the last row seat.

[0003] Patent Document 1 describes a mechanism for switching the middle row seat, that is, the second seat, from the seated state to a walk-in state in which the backrest (seat back) is tilted forward to facilitate access to the last row seat, that is, the third seat, and a mechanism for switching to a fully reclined state in which it is even easier to pass through than the walk-in state by lifting the middle row seat from the rear end of the seat surface and tilting it forward. This fully reclined state is called a tumble state. It is described that the passenger in the third seat can switch from the seated state to the walk-in state by operating a first knob (see reference numeral 70 in Patent Document 1) attached to the second seat, and can slide forward in this walk-in state (Patent Document 1

[0036] ~

[0038] ). Also, by operating a second knob (see reference numeral 72 in Patent Document 2), the back frame of the backrest can be overlapped on the seat cushion of the seat surface, and it can be switched to the tumble state (Patent Document 1

[0039] ~

[0042] ).

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, if a plurality of operating means such as knobs and levers for changing the position of the seat are provided, when a passenger changes between the walk-in state and the tumble state, it is easy to be confused about which one to operate and how. In some cases, when a passenger notices one operating means, they may not notice the existence of another operating means and may even remain unaware of the existence of the switching function. In particular, in a vehicle equipped with a three-row seat that can accommodate a large number of passengers, it is often the case that a person who rides in the vehicle for the first time operates it, and the risk of confusion is even higher.

[0006] Therefore, an object of the present invention is to enable a passenger to easily operate without mistake when switching the state of moving the seat of the vehicle.

Means for Solving the Problems

[0007] In order to solve the above problems, the present invention provides a first seat having a seat surface portion and a back surface portion, a second seat disposed behind the first seat, operating means provided on the first seat, and the operating means can change the first seat to a first state in which the passenger can move the seat forward from the reference state where the passenger sits on the seat surface portion and the back surface portion, and a second state in which the seat surface portion and the back surface portion can be integrally rotated from the reference state, and adopts a vehicle seat that can be changed using a common operating member.

[0008] Since the first state and the second state can be switched using a common operating member, it is possible to surely prevent a situation where the passenger is confused about which operating member to use during operation. In addition, this can reduce the number of operating members, thereby reducing the occupied area in the floor and also reducing the number of parts, which can contribute to cost reduction.

[0009] As a specific operation in the present invention, the change to the first state is performed by an operation of moving the operation member forward, The change to the second state can adopt a form in which the operation member is moved backward. Since the respective states assigned to the first state and the second state and the front-back relationship can be made intuitive, it is less likely to cause confusion in operation and easier to handle.

[0010] As a specific form of the operation member in the present invention, One end thereof is connected to a rotating shaft rotatably supported by the first sheet, and a gripping portion for operation is provided at the other end, The change to the first state is performed by an operation of rotating the other end of the operation member forward, The change to the second state can adopt a form in which the other end of the operation member is rotated backward. In other words, it can be switched by an operation of tilting the gripping portion forward and backward, and it is possible to intuitively switch to different states with one operation member.

[0011] As a specific embodiment in the present invention, the form that can be realized in the first state is a walk-in state in which the back surface portion is inclined forward by a predetermined angle with respect to the seat surface portion and the seat surface portion is slid forward by a predetermined distance from the reference state, The form that can be realized in the second state can adopt a form in which the back surface portion is inclined forward by an angle larger than the predetermined angle with respect to the seat surface portion and the rear end of the seat surface portion is lifted upward from the reference state, which is a tumble state. In many cases, the walk-in state in which the operation is performed while sitting on the seat, and the tumble state in which there is no one sitting on the seat and the person sitting on the seat behind or the person trying to open the door and enter operates to temporarily retract the seat are assigned to one operation member and switched, so that the operation member to be operated is less likely to be confused.

[0012] Furthermore, the operation member is, A walk-in actuator that operates a first link mechanism corresponding to switching to the first state, When adopting a form provided with a tumble actuator that operates a second link mechanism corresponding to switching to the second state, the assigned state and the direction of the operating member can be made to coincide, making it intuitive and easy to operate. If the operation of moving the operating member forward is assigned to switching to the first state that can realize the walk-in state, it is easy to operate because it coincides with the direction of the body movement of the occupant bending forward while sitting. On the other hand, if the operation of moving the operating member backward is assigned to switching to the second state that can realize the tumble state, even a person sitting in the rear seat can easily operate by pulling the operating member forward, and confusion can be avoided.

[0013] In practicing this invention, a three-row seat vehicle having an intermediate row seat immediately behind the driver's seat and the front passenger seat, a last row seat immediately behind the intermediate row seat, and an entrance / exit door shared by the intermediate row seat and the last row seat on the side of the intermediate row seat, A vehicle in which the first seat is arranged as the intermediate row seat and the second seat is arranged as the last row seat can be adopted.

Effect of the Invention

[0014] By using the vehicle seat according to this invention, when switching the seat from the reference state to two different states, there is no confusion about which operating means to choose, and an intuitive and easy-to-use operation can be realized.

Mode for Carrying Out the Invention

[0016] Embodiments of the present invention will be described with reference to the drawings. The present invention is a vehicle seat provided inside a vehicle and a vehicle equipped with the same. In this embodiment, a vehicle with a three-row seat is assumed. In a vehicle with a three-row seat, boarding and alighting doors are provided for the driver's seat and the front passenger seat in the front row, respectively, and for the seats behind, there are many designs with one boarding and alighting door on both the left and right sides or on either the left or right side. The vehicle seat has a first seat 10 including a seat surface portion 11 and a backrest portion 12, a second seat 20 disposed behind the first seat 10, and an operating means 30 provided on the first seat 10.

[0017] As a vehicle equipped with the vehicle seat according to the present invention, it is necessary to be a vehicle having at least two rows of seats in the front-rear direction, and it can be preferably used in a vehicle having three rows of seats in the front-rear direction. In addition, it is preferably used in a vehicle in which the number of boarding and alighting doors provided on the left and right sides of the vehicle is less than the number of rows of seats. That is, in a vehicle having two rows of seats, it is a vehicle having one boarding and alighting door on each of the left and right sides. In a vehicle having three rows of seats, it is a vehicle having at least two boarding and alighting doors on either the left or right side.

[0018] Examples of vehicles having the vehicle seat according to the present invention are shown in FIGS. 1(a) and 1(b). FIG. 1(a) is a side view seen from the left side of the vehicle, the front passenger seat N side. FIG. 1(b) is a plan view seen from above the vehicle. It is a three-row seat vehicle equipped with an intermediate row seat M immediately behind the driver's seat D and the front passenger seat N, and a last row seat L immediately behind the intermediate row seat M. The first seat 10 constituting the vehicle seat according to the present invention is at least a part of the seats in the intermediate row seat M. In this example, among the intermediate row seats M, the seat on the front passenger seat N side is the first seat 10. This first seat 10 is a seat in a position where it needs to be deformed and displaced because a passenger getting on and off the second seat 20, which is the last row seat L, cannot pass through as it is when getting on and off through the boarding and alighting door 2 adjacent to the intermediate row seat M (the first seat 10).

[0019] The first seat 10 is provided with operating means 30. An operating member 31 for switching the operating means 30 is provided at a position where it can be operated by a passenger sitting on the first seat 10. Further, it is preferably provided at a position where it can be easily reached when the boarding and alighting door 2 is opened. This is because it is necessary that a person who intends to sit on the second seat 20 can easily operate the first seat 10 to switch it to a tumble state described later. For this reason, the operating member 31 is preferably provided on the side of the boarding and alighting door 2 of the first seat 10.

[0020] The first seat 10 is in a reference state A during normal times, and the operating means 30 can be changed to a first state B in which the first seat 10 can be moved forward and a second state C in which the seat surface portion 11 and the back surface portion 12 can be integrally rotated from the reference state A. The differences among these reference state A, first state B, and second state C indicate the differences in the displaceable states of the seat surface portion 11 and the back surface portion 12 of the first seat 10. The reference state A is a normal state in which a passenger sits on the seat surface portion 11 and the back surface portion 12 of the first seat 10. This state is shown in Fig. 2(a). The seated passenger can operate the operating member 31 of the operating means 30 while remaining seated.

[0021] The change to the first state B is preferably performed by an operation of moving the operating member 31 forward. It is desirable that this is a configuration that can be easily operated by a passenger sitting on the first seat 10. On the other hand, the change to the second state C is preferably performed by an operation of moving the operating member 31 backward. By being opposite to the change to the first state B, the difference in operation becomes clear. A specific form of the operating member 31 for realizing such a configuration is shown in Fig. 3. One end 31a of the operating member 31 is connected to a rotating shaft 32 rotatably supported by the first seat 10, and a gripping portion 33 for operation is provided at the other end 31b. The first function is performed by an operation of rotating the other end 31b of the operating member 31, that is, the gripping portion 33, forward. By this operation, it is switched to the first state B. On the other hand, the second function is performed by an operation of rotating the other end 31b of the operating member 31, that is, the gripping portion 33, backward. By this operation, it is switched to the second state C.

[0022] In this embodiment, the form that can be realized in the first state B in which the first seat 10 is switched is a walk-in state in which the backrest 12 is inclined forward by a predetermined angle with respect to the seat surface portion 11 and the seat surface portion 11 is slid forward by a predetermined distance from the reference state A. As a result, the space behind the first seat 10 becomes empty, so that the operator can operate the operating means 30 while the passenger is seated on the first seat 10, making it easier to get on and off the second seat 20. This state is shown in Fig. 2(b).

[0023] In this embodiment, the form that can be realized in the second state C in which the first seat 10 is switched is a tumble state in which the backrest 12 is inclined forward by a larger angle than a predetermined angle with respect to the seat surface portion 11 and the rear end of the seat surface portion 11 is lifted upward from the reference state A. The tumble state is a large-tip state in which the seat surface portion 11 and the backrest 12 are integrally rotated to tip the rear end of the seat surface portion 11 forward, making it even easier to pass through than the walk-in state. The transition to the tumble state realized in the second state C can be performed when there is no passenger seated on the first seat 10, making it even easier to get on and off the second seat 20 than in the walk-in state. The situation of performing the transition is shown in Fig. 2(c), and the situation of entering and exiting in the tumble state is shown in Fig. 2(d). The rear end of the seat surface portion 11 separates from the tumble latch 75 and tips forward, greatly expanding the space.

[0024] An example of the arrangement of the structure of the first seat 10 that realizes such a change in state is shown in FIG. 4. It is a perspective view of the first seat 10 as seen from the entire vehicle surface. On the right side in the figure, that is, on the left side for the seated passenger, an operation member 31 is provided. The operation member 31 is connected to a first link mechanism 40 that performs a reclining operation. On the other hand, an angle limit release wire 61 that is connected via the operation member 31 and the mechanism passes under the seat surface 11 and is connected to a forward tilt angle limit release mechanism 60 provided on the opposite side of the seat. The movement of the backrest part 12 that is tilted forward is connected to a tumble latch release mechanism 70 and rotates a rotation engaging part 72 attached to a turntable 71 described later. Pushed by this rotation engaging part 72, a tumble latch release wire 74 that extends downward is pulled up and disengaged from a striker 76 of a tumble latch 75 provided under the seat surface 11, and the latch is released.

[0025] An example of a mechanism that performs a reclining operation to achieve a walk-in state that can be realized from the reference state A to the first state B and an operation to achieve a tumble state that can be realized from the reference state A to the second state C by a common operation member 31 is shown in FIG. 5. A rotating member 34 that is directly connected to the operation member 31 and rotates according to the inclination of the operation member 31 is in contact with a reclining stopper 43 and is connected to a first link mechanism 40 that releases the reclining, and is also in contact with a second link mechanism 50 that is connected to the forward tilt angle limit release mechanism 60 and the tumble latch release mechanism 70.

[0026] The situation in the reference state A is shown in Fig. 5(a). The reclining stopper 43 is rotatable about the rotation axis 32, and a clockwise force in the figure is always applied by an internal spring (not shown). The walk-in action portion 41 protruding to the left side of the rotating member 34 is locked by a recess 42 provided in the upper portion of the reclining stopper 43. A first link mechanism 40 is rotatably attached to the end portion (left side in the figure) of the reclining stopper 43 on the side opposite to the rotation axis 32 via a joint portion 44. This first link mechanism 40 is connected to an angle limit release wire 61, and when the first link mechanism 40 is lowered, the reclining of the backrest portion 12 is released. Further, a slide hole 46 is provided in the first link mechanism 40 in the longitudinal direction, and a hook portion 57 is arranged at the lower end portion of the slide hole 46. When the first link mechanism 40 moves up and down, the hook portion 57 slides along the slide hole 46 without following it.

[0027] The situation when changing to the first state B is shown in Fig. 5(b). When the rotating member 34 is tilted to the left side in the figure, that is, forward, the walk-in action portion 41 pushes down the reclining stopper 43 and pushes down the first link mechanism 40. When this first link mechanism 40 is pushed down, the reclining is released and it becomes possible to tilt forward to a predetermined angle. Also, a slide stopper (not shown) that stops the front-back slide of the first seat 10 is released, and the first seat 10 can be slid forward. Thus, the change to the first state B is completed. Thereby, the operation to the walk-in state can be realized.

[0028] The situation when changing to the second state C is shown in Fig. 5(c). A convex portion 36 protruding downward from the rotating member 34 is engaged with a locking portion 52 protruding upward from the second link mechanism 50. The second link mechanism 50 has, in addition to a head portion 53 having a locking portion 52 protruding upward, arm portions 54, 55 on the left and right, and is rotatable with respect to a central rotation axis 56. However, it is not biased and remains in its position until a force is applied. When the rotating member 34 is tilted to the right side in the figure, that is, backward, a tumbling action portion 51 at the tip of the convex portion 36 pushes the second link mechanism 50 in the direction of left rotation. When the left arm portion 54 is lowered, a hook portion 57 provided at the tip thereof descends downward. The hook portion 57 is caught by the lower end portion of the slide hole 46, and the first link mechanism 40 is also lowered downward. Thereby, the reclining is released as described above. On the other hand, when the right arm portion 55 is lifted, an angle limit release wire 61 attached to a fixing portion 58 at the tip of the arm portion 55 is pulled up, and a forward tilt angle limit release mechanism 60 provided on the opposite side of the seat is released. Along with this, the tumble latch release mechanism 70 is also released in a chain reaction. The change to the second state C is completed as described above.

[0029] An embodiment of a mechanism for interlockingly releasing the forward tilt angle limiting mechanism 60 and the tumble latch release mechanism 70 will be described with reference to FIGS. 6(a-1) to (c-2) and FIGS. 7(a-1) to (c). FIGS. 6(a-1) to (c-2) show the mechanism procedures until the forward tilt angle limiting mechanism 60 is released. FIG. 6(a-1) is a schematic view showing the operation of the backrest portion 12 in a state where reclining is released. FIG. 6(a-2) is an enlarged view of the periphery of the forward tilt angle limiting mechanism 60 provided at the joint portion between the backrest portion 12 and the seat portion 11. The turntable 63 is provided at the joint portion of the backrest portion 12 with the seat portion 11 and rotates corresponding to the inclination of the backrest portion 12. A protrusion 64 is provided on the outer periphery of the turntable 63. This protrusion 64 moves according to the rotation of the turntable 63 and hits a stopper 65 provided above the forward tilt angle limiting mechanism 60 provided under the turntable 63. This state is the limit angle at which the forward tilt can be performed with the normal reclining released. FIG. 6(b-1) is a schematic view of this situation where the backrest portion 12 is reclined forward to the limit. FIG. 6(b-2) is an enlarged view of the periphery of the forward tilt angle limiting mechanism 60 in a situation where the protrusion 64 hits the stopper 65. The form that can be realized in the first state B stops at the displacement so far. Incidentally, by separately sliding the entire first seat 10 forward, it becomes suitable as a walk-in state.

[0030] On the other hand, in the second state C, when the angle limiting release wire 61 is pulled up by the second link mechanism 50, the forward tilt angle limiting mechanism 60 connected through under the seat is pivoted about the pivot axis 66 and the stopper 65 side is pulled down. As a result, the protrusion 64 becomes further rotatable, and it becomes possible to further rotate the backrest portion 12 connected to the protrusion 64. That is, it is possible to make the backrest portion 12 tilt forward further than the above-mentioned limit angle. FIG. 6(c-1) is a schematic view showing that state. FIG. 6(c-2) is an enlarged view in a state where the forward tilt angle limiting mechanism 60 is released. It is preferable that the backrest portion 12 can be tilted until it contacts the seat portion 11 because it becomes easy to move to the tumble state described later.

[0031] In the second state C, when the forward tilt angle limiting mechanism 60 is further released, the tumble latch release mechanism 70 on the opposite side of the seat is also released in a chain reaction. The procedure of this mechanism will be described with reference to FIGS. 7(a-1) to (c). FIG. 7(a-1) is a schematic diagram of the state where the above-mentioned forward tilt angle limiting mechanism 60 is released and the seat is tilted at an angle greater than the above-mentioned limit angle, which is the state between FIGS. 6(b-1) and 6(c-1). At this time, in the tumble latch release mechanism 70, the rotating engagement portion 72 protruding axially from the disk surface of the rotating disk 71 that rotates around the rotation axis 62 together with the backrest portion 12 also rotates. An enlarged view of the tumble latch release mechanism 70 in this situation is shown in FIG. 7(a-2). On the other hand, both arm portions 73 attached so as not to be interlocked with the rotation of the backrest portion 12 extend in the diametrical direction from the rotation axis 62. One end (the left side in the figure) of both arm portions 73 extends to a position (contact point 77) that collides with the rotating engagement portion 72, and a tumble latch release wire 74 is connected to the other end of both arm portions 73 at the connection point 78. The tumble latch release wire 74 is connected to a tumble latch 75 provided under the seat surface 11, and the tumble latch 75 is fitted with a striker 76 provided on the floor surface. When the backrest portion 12 is tilted all the way to the situation in FIG. 7(b-1), the rotating engagement portion 72 hits the contact point 77 of both arm portions 73 and pushes it, rotating both arm portions 73 in the counterclockwise direction in FIGS. 7(a-1) to (c). When the other end of both arm portions 73 is pulled up, the tumble latch release wire 74 connected at the connection point 78 is pulled up. This situation is shown in the enlarged view of FIG. 7(b-2). When the tumble latch release wire 74 is pulled up, the fixation between the striker 76 and the tumble latch 75 is released. Then, the first seat 10 can be lifted from the seat surface 11. In addition, in order to be easily returned after the passenger gets in and out, it is preferable that the front lower part of the first seat 10 is fixed to the floor surface via a rotation axis 79 that rotatably holds the seat surface 11. Thereby, it is possible to lift from the rear lower part of the first seat 10 and integrally rotate the seat surface 11 and the backrest portion around the rotation axis 79 to shift to a tumble state where the whole is tilted forward greatly. A side view of this situation is shown in FIG. 7(c).

[0032] In any case of the first state B and the second state C, when the passenger has completed entering and exiting, the seat surface portion 11 and the backrest portion 12 are returned to their original positions, and the operation member 31 is also returned, thereby returning to the reference state A again. When returning from the second state C to the reference state A, when the seat surface portion 11 is lowered, the tumble latch 75 is fitted into the striker 76 and fixed, and when the backrest portion 12 is returned to its original position, the forward tilt angle limiting mechanism 60 also returns to its original state (from FIG. 6(b-2) to (a-2)), and returns to an angle more suitable for the original seating than the above-mentioned limit angle.

[0033] For a vehicle seat such as this, a three-row seat vehicle equipped with the first seat 10 as an intermediate row seat and the second seat 20 as a last row seat can be switched to either the first state B or the second state C by operating the common operation member 31, preventing confusion about which member to operate. The form that can be realized in the first state B can be set as a walk-in state, and the form that can be realized in the second state C can be set as a tumble state. With such a configuration, while the operation member 31 can be operated while seated on the first seat 10 to change to the first state B to realize the walk-in state, in a state where there is no person seated on the first seat 10, the same operation member 31 can be operated in a different direction to change to the second state C to realize the tumble state. If the operation direction of the operation member 31 is tilted forward when changing to the walk-in state and tilted backward when changing to the tumble state, it conforms to the intuition of the operation, preventing confusion and being particularly easy to handle.

[0034] As described above, various embodiments have been described with reference to the drawings, but it goes without saying that the present invention is not limited to such examples. It is obvious that those skilled in the art can conceive of various modification examples or correction examples within the scope described in the claims, and it is naturally understood that those also belong to the technical scope of the present invention. Also, within the scope not departing from the gist of the invention, the components in the above embodiments may be arbitrarily combined.
