Text navigation

With Kotobuki Seating’s bespoke LCD navigation device, status confirmation messages for 40 safety and security items can be displayed. The system is based on universal design concepts in an effort to provide ease of use and safety.

If an error occurs, the problem is displayed on the screen. Most errors can be easily resolved by following the instructions displayed.

Safe design to prevent accidents and incorrect operation

Each component is fitted with safety devices to ensure the equipment can be operated easily and efficiently. When an extending or retracting operation has not been carried out properly, operation pauses and a status message is displayed on a remote device, together with guidance on how to handle the problem appropriately

  • Removable side rails

    ①Removable side rails

    When the seating is retracted, the removable side rails along the last few rows are removed. If someone forgets to remove the side rails and the retracting operation is performed with them still attached, the retracting operation is automatically paused.

  • seat fold-down operation

    ②Seat fold-down operation

    If belongings or other items are on the deck of the unit, and impede the seating folddown operation, a status message is displayed.





  • Sensor-equipped front panel

    ③Sensor-equipped front panel

    If sensors on the front panel detect an obstacle that would impede the advance of the unit, the extending operation is paused to prevent accident or breakage.

  • Upper level aisle doors

    ④Upper level aisle doors

    An interlock mechanism prevents the doors from opening or closing when the unit is retracted. The system is designed so that the unit can only be extended or retracted when the doors are locked. (Requires co-ordination with the architect and builder.)

  • Connector box

    ⑤Connector box

    When the hand-held controller is connected to the connector box, the audio guidance will begin.

One of the world’s best systems for straight opening

Using a non-friction drive system, drive links extend to open the rows meaning no direct load is placed on the floor.The responsive drive links are able to extend the unit perfectly straight, adjusting to maintain flawless alignment. Thisreduces wear and tear on the unit, giving smooth, trouble free operation and extending the life-expectancy of the system.

2 different types of load dispersal system can be used depending on the circumstances

Drum Unit (DU) non-friction drive system

A drive link wound up around the drum unit is connected to the first row of the retractable seating. By rotating the drum with a motor and moving the drive link in and out horizontally, the extending or retracting operation is performed. As there is no impact from the floor, travel is in a straight line and even possible over ice. Recommended number of levels: 10 or more

The roller prevents damage to the floor

6-Wheel Drive (6WD) drive dispersion system

The seating is extended and retracted using a single motor to drive six distributed wheels. Grip to the floor is across a wider area, minimizing the impact on the floor construction. This design also provides straight alignment of the system, giving smooth, trouble-free operation and increasing longevity. Recommended number of rows: Up to 10

  • Removable side rails

    ②Removable side rails

    When the seating is retracted, the removable side rails along the last few rows are removed. If someone forgets to remove the side rails, and the retracting operation is performed with them still attached, the retraction is automatically paused.

  • Hinged storage type steps

    ③Hinged steps

    The steps are rotated and stowed on the first row platform. As the steps do not move when people step on them, they can be walked over safely.

  • Fixed steps

    ④Fixed steps

    Fixed steps are installed along the front-to-back aisles to make it easy for people to walk to their seats, and are set to half the depth of each level. The steps help to maintain a constant walking rhythm.

  • Sensor-equipped front panel

    ⑤Sensor-equipped front panel

    If sensors on the front panel detect an obstacle that would impede the advance of the unit, the extending operation is paused to prevent accident or breakage.

  • Aisle lighting (LED)

    ⑥Aisle lighting (LED)

    For audience convenience and safety, aisle lighting is provided in the armrest to the right or left of each aisle as standard. The LED lamps emit discrete, diffused lighting over a wide area, so that they do not produce glare even when viewed from the stage.

  • Side guard panels

    ⑦Side guard panels

    The side guard panels prevent spectators and foreign objects from transgressing underneath the unit. The panels are a high quality design, composed of aluminum sandwich panels.

  • Motorized folding side rails

    The side rails along the last few rows, which would normally need to be removed before the unit is closed, are folded away using a motorized mechanism. This reduces the hassle and time associated with set up and removal, and eliminates the need to work at height. In addition, unlike removable side rails, no storage location is required for the side rails following removal.

  • Wheelchair Space

    A cutout in the body of the retractable seating can create space for wheelchair seating.

  • Automated Upper Locking System

    Lock pins move up and down in as the seating units open and close. By fastening each row to the one above, they help to minimize vibration.

Three models are suitable for all kinds of venues, from multi-purpose halls to school lecture halls and gymnasiums. The standard series is the most frequently chosen option from our lineup.
