Power Positioning Functions


Sky-High Power Elevating Seat

Reach new heights with the power elevating seat. The seat is mounted into the chassis and can be raised stepless up to 40 cm. This provides the users with a better view and better access to their surroundings.

50-Degree Center of Gravity Tilt System

The center of gravity tilt system ensures pressure relief and a high degree of comfort. The tilt can also be used when traveling down a slope to compensate for the negative seat angle. This provides a safer and more stable seating position.

Biomechanical Power Recline and Elevating Legrest

180° power recline together with 180° power elevating legrest, total flat position allows the user to lie down straight. With the biomechanic design, the seat traverses with body movement, minimizing the effect of shearing force, keeping all the supports in the correct alignment with the body, and ensuring sitting stability.

Remark :
* Nominal seat width is measured the width of seat cushion at 120mm in front of the backrest.
This value is mainly used in the product ordering process.
** Nominal seat depth is measured from the front end of the seat cushion to the back cushion. This value is mainly used in the product ordering process.
*** Drive range/ Ability to climb rated slope are estimated based on the following conditions: 20℃~35℃, 140 kg occupant, brand new fully charged batteries and driving on the flat road.
– Evo Lectus LR satisfies the requirements according to EN 12184 and the maximum occupant mass is 140 kg.
– The actual product specifications differ from the data in the table by ±1 cm ±0.5 kg.
