DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments of the present invention will be specifically described below with reference to the accompanying drawings. First, in the perspective view of FIG. 1, reference numeral 10 denotes an instrument panel provided in a front portion of a vehicle compartment,
Reference numeral 12 denotes a meter coaster provided in front of a driver's seat (not shown) of the instrument panel 10, reference numeral 14 denotes a passenger seat disposed in a vehicle cabin, and reference numeral 16 denotes an instrument panel 10 which can be moved back and forth in the vehicle longitudinal direction. The assist grip 18 provided is a steering wheel schematically showing only the wheel cover by a dashed line.

As shown in FIGS. 1 and 3, the assist grip 16 has a substantially rectangular shape in plan view, and a pair of horizontal grips for holding parallel vertical sides 20 in the front-rear direction of the vehicle body from left and right, respectively. As shown in FIG. 3, the rollers 22 and 24 and the vertical rollers 26 in contact with the lower side of each vertical side 20 are supported so as to be able to smoothly advance and retreat in the vehicle longitudinal direction. In addition, the horizontal rollers 22 and 24,
The vertical roller 26 is formed by an aggregate and a bracket (not shown) inside the instrument panel 10.
Each is rotatably supported.

[0008] A front side 28f of the parallel side extending in the vehicle width direction of the assist grip 16 has a piston shaft of a hydraulic cylinder device 30 constituting an actuator for moving the assist grip forward and backward in the vehicle longitudinal direction. 32 are connected. The lateral side 28r behind the assist grip 16 serves as an effective grip member for the occupant sitting on the passenger seat 14 as described later.

The hydraulic cylinder device 30 is controlled by an electromagnetically operated control valve 34, which is selectively driven by a controller 36 to one of a first position 34a and a second position 34b. When the control valve 34 is driven to the first position 34a shown in FIG. 3, the working chamber 38 of the hydraulic cylinder device 30 is connected to the oil tank or the reservoir 42 through the discharge passage 40, while A pressure oil supply passage 46 communicating with a pump 44 and the working chamber 38
Communication with the is blocked. The pressure oil supply passage 46 is provided with a normal pressure regulating valve 48 and a one-way valve 50.

The controller 36 includes an output signal of an acceleration sensor (G sensor) 52 provided at an appropriate position on the vehicle body,
An ON / OFF signal of a forcible storage switch 54 for forcibly storing the assist grip 16 in the instrument panel 10 and a signal of an operation switch 56, which will be described in detail later, are supplied.

The operation of the controller 36 is as shown in the flowchart of FIG. Program is checked off forced storing switch 54 in the previous Dzu Step S ₁ to start. Y when the switch 54 is closed
For ES, the process proceeds to step _{S 2,} the controller 36
Thereby, the control valve 34 is controlled to the first position 34a. The forcible storage switch 54 is used when the vehicle is in an urban area or a general road,
When the driver does not want to use the assist grip 16, such as when driving on an expressway, the driver closes the seat by the driver's will.

When the control valve 34 is in the first position 34a, as shown in FIG.
Since the working chamber 38 communicates with the atmosphere through the discharge passage 40, the piston shaft 32 is held at the illustrated storage or rest position by the return spring 58. Accordingly, the assist grip 16 connected to the piston shaft 32 is retracted and stored inside the instrument panel 10, and the rear side of the rear side 28r is substantially flush with the rear side of the adjacent instrument panel. , So that the aesthetics of the cabin will not be impaired. Since the assist grip 16 is stored inside the instrument panel 10, the fixed assist grip 1 is fixed in front of the passenger seat 14.
As compared with the conventional structure in which the protrusion 6 is protruded, it is possible to increase the free space of the passenger compartment and to improve the livability without hindering the getting on and off.

[0013] Next, in step S _1, the case of NO where the force storing switch 54 is opened, step actuator or hydraulic cylinder unit 3 proceeds to S ₂
A check is made to see if 0 is in the storage location. As means for checking whether or not the actuator 30 is in the storage position, the state of the drive signal given to the control valve 34 by the controller 36, a stroke sensor provided in the hydraulic cylinder device 30, or the position of the assist grip 16 directly A signal from a limit switch that is opened and closed can be used as appropriate.

[0014] The actuator 30 in step _{S 3}
If is YES in the retracted position, the step proceeds to S _4, is checked whether the signal of the operation switch 56. Hope occupant use of the assist grip 16 seated in the passenger seat 14, by operating the operation switch 56 when the signal is generated (YES), step goes to S ₅ the controller 36
As a result, the control valve 34 is driven to the second position 34b.

When the control valve 34 is driven to the second position 34b, the working chamber 38 of the hydraulic cylinder device 30
6, the hydraulic oil is supplied from the hydraulic pump 44 to the working chamber 38, the return spring 58 is compressed, and the piston shaft 32 is displaced rightward in FIG. The rightward movement of the piston shaft 32 causes the assist grip 16 to advance into the passenger compartment toward the passenger seat 14 as shown by a dashed line in the figure, and the rear lateral side 28r of the assist grip 16 is mainly for the occupant. It is an effective clip member.

[0016] On the other hand, in step S _4, when the occupant is not issued is the signal without operating the operation switch 56, step proceeds to S _6, the acceleration sensor 52 is here
Is checked to see if the output is greater than or equal to the set value. The acceleration sensor 52 includes an appropriate acceleration detection device that detects the magnitude and direction of the acceleration by detecting, using a photoelectric device or the like, a relative displacement between the inertial body generated by the acceleration and a supporting member that supports the inertial body. And an acceleration sensor capable of detecting vertical, lateral, and longitudinal acceleration is preferably used.

[0017] In step S _6, for example, by rough road running is that the acceleration in the vertical direction exceeds a set value is detected (YES), program control valve 34 by automatically controller 36 proceeds to S ₅ Driven to the second position 34b, the assist grip 16 advances to the operating position as described above. On the other hand, during steady running of not detected acceleration set value or more by the acceleration sensor 52 (NO) for example flat road, step proceeds to S _2, the controller 3
6, the control valve 34 is kept in the first position, so that the actuator 30 is kept in the retracted or rest position.

[0018] detects the acceleration acceleration sensor 52 is equal to or greater than the set value in the operation switch 56 is operated or step S ₆ in step S ₄ as in step S
₅ by the control valve 34 is driven to the second position 34b, the actuator 30 is actuated, blogs ram is again returned to step _{S 1,} then determines NO in step _{S 3,} step proceeds to _{S 7.}

[0019] In step _{S 7,} is examined whether the signal by the operation of the operation switch 56, if the operation switch 56
If is NO not operated, the control valve 34 in step S ₅ is held in the second position 34b, the assist grip 16 for holding the subsequently state that advances in the use position. Further, in step _{S 7,} the operation switch 56 is operated (YES) the program proceeds to _{S 2,} the actuator 30 the control valve 34 by the controller 36 is driven to the first position 34a is returned to storage or resting position .

[0020] Therefore, when is advanced the assist grip 16 by operating the operation switch 56 in step S ₄ in the use position, by operating the operation switch 56 again, it is possible to store the assist grip 16.
Further, immediately assist grip 16 when the assist grip 16 if that advances in the use position, for example, uneven ground the through or the acceleration of the set value or more ends of the sharp turn is not detected by the operation of the acceleration sensor 52 in step S ₆ instead of but stored, so so that the first assist grip 16 operation switch 56 is operated in step S ₇ is stored, it becomes less acceleration set value while gripping the grip mountain road or the like, or disappearance When this happens, there is no problem that the assist grip 16 is automatically retracted and a finger is pinched.

The above-described operation mode of the controller 36 is merely an example, and the present invention can be implemented by appropriately changing or modifying the above-described flowchart. For example, the advancement omit Step S ₄ to use the position of the assist grip 16, is solely dependent on the operation of the acceleration sensor 52, i.e. may be directly connected to the step S ₃ and the step S _6. In addition, it is desirable that the forced storage switch 54 and the operation switch 56 are provided at appropriate positions in the vehicle compartment, which can be easily operated by an occupant sitting in the passenger seat 14 as a matter of course.

Further, the shape of the assist grip 16 is
The shape of the actuator 30 is not limited to the illustrated rectangle but may be an appropriate shape such as a T-shape, an L-shape, and a U-shape. A screw-and-nut type actuator including a nut fixed to the grip 16 and other appropriate actuators can be used instead. Furthermore, the present invention can be widely applied not only to all-wheel drive vehicles but also to ordinary passenger cars, trucks, van-type vehicles, and the like.

As described above, the vehicle cabin structure according to the present invention has an assist grip provided on an instrument panel in front of a passenger seat provided in the vehicle cabin so as to be able to advance and retreat in the vehicle longitudinal direction. A first position where the assist grip is stored in the instrument panel in accordance with a running state of the vehicle or a manual operation of an occupant, and a second position where the assist grip advances toward the passenger seat side in accordance with a running state of the vehicle or an occupant's manual operation. And an actuator that selectively drives the crab, and when traveling on rough roads or rough terrain or when a passenger on the passenger seat desires, the above-mentioned assist grip advances just before the passenger on the passenger seat, so that the usability is extremely high. Good, and when not necessary, the assist grip is stored in the instrument panel, so it is compared to the conventional fixed grip. Without hinder passenger, also have the advantage not impaired livability of the passenger compartment space, it is practically very valuable.
