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 a better access to their surroundings.

Biomechanical Power Recline and Elevating Legrest

Because it is not always easy to adapt to a new living situation, the EVO Lectus is designed with various biomechanical principles in mind, to help the user with the transition. It includes power recline and power articulating elevating legrests. The seat will traverse with the body as the user reclines, thereby reducing the sheer force. Most importantly, it keeps all the supports in the correct alignment with the body.

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.

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℃, 136 kg occupant, brand new fully charged batteries and driving on the flat road.
– The actual product specifications differ from the data in the table by ±1 cm ±0.5 kg.
– The actual product specifications may vary according to different configurations.
