Power Positioning Functions

30 cm Power Seat Lift

The seat lift is centrally mounted into the chassis. With this lift, the seat can be raised step less up to 300 mm. This enables the user to have more freedom of movement, not only in the horizontal area but also in the vertical area.

45 degree Centre Gravity tilt

The centre gravity tilt ensures pressure relief and a high degree of comfort. The tilt can also be used when driving down a slope for compensating the negative seat angle. This provides a more stabile seat position and safe driving.

Biomechanical Power Recline

Because it is not always easy to adapt to a new living situation, the MID Lectus is designed with various biomechanics positioning functions to help the user with the transition. It includes power backrest recline and articulated elevating legrest. The seat will traverse with the body, thereby reducing the sheer force to a minimum and most importantly, keeping all the supports in the correct alignment with the body.

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.
– Mid Lectus 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.
– The actual product specifications may vary according to different configurations.
– Karma reserves the right to modify information herein without further notice.
