Seat Glossary

 

Do you have questions about our products? Please see below for descriptions of the most important functions of your ISRI® seat.

Our brochure Fit for Drive contains important information about healthy sitting.

Horizontal adjustment

  • Pull the adjusting lever upwards and adjust the ISRI® seat to the desired position.
  • The ISRI® seat should be adjusted so that you can reach the pedals comfortably and press them all the way through.
  • Press your shoulder against the backrest, so that you can reach the steering wheel with slightly angled arms.
  • Release the lever >  the horizontal adjustment must lock audibly.

 

Pneumatic Height Adjustment

  • Pull up the lever > the ISRI® seat moves upwards. Push down the lever > the ISRI® seat moves downwards.
  • At the correct seat height the thighs should rest comfortably on the seat cushion while the legs are a resting position. You should be able to press the pedals all the way through, without extensive pressure building between the thigh and the seat cushion.

 

Tilt adjustment

  • Pull up the lever and move the ISRI® seat into the desired position by leaning foward or backward against the seat/backrest.
  • Please ensure that the seat angle is adjusted so that the thighs rest on the seat cushion without exerting too much pressure.
  • If possible, always choose a negative seating position.
  • Release the lever >  the lever must lock audibly.

 

Seat cushion depth adjustment

  • After adjusting the seat tilt, check the seat cushion depth.
  • Lift the lever up and the seat cushion can be moved forwards or backwards. The ideal position is when the distance between the back of the knee and the front edge of the seat cushion is approximately two to three cm.  This allows you to remove your foot from the pedal and place it near the seat - thus reducing the pressure on the back of the knee.
  • Release the lever >  the lever must lock audibly.

 

Pneumatic Lumbar Support (LWS/IPS)

  • If your ISRI® seat is equipped with pneumatic lumbar support, you can adjust the backrest contour optimally to your body.
  • Adjust the lumbar support so that you avoid a hunchback position.
  • The natural form of the lumbar area should be supported.
  • The chambers of the pneumatic lumbar support can be inflated or deflated independently.

 

Backrest adjustment

  • Lift up the lever and move the backrest in the desired position by using your body weight.
  • Adjust the backrest tilt so that you can reach the steering wheel with your arms slightly angled.
  • You will feel the shoulder support of the backrest when sitting in a normal position.
  • Release the lever >  the backrest must lock audibly.

 

Shoulder height adjustment

  • ISRI® seats provide higher safety and comfort levels through additional shoulder height adjustment.
  • Lift up the lever and place the upper backrest in the desired position by leaning your head backwards.
  • For your own safety please ensure that the distance between the head and the back rest is approximately two centimeters.

 

Vibration dampeners

  • The vibration dampeners of your ISRI® seat (comfort position) can be adjusted variably from “soft” to “hard” enabling their optimal adjustment for each driving situation.
  • Lift the lever upwards (seat comfort:  “soft”), press the lever downwards (seat comfort:  „hard“).



Attention:
When driving in poor road conditions the vibration dampeners must be adjusted tightly enough to avoid the seat hitting the floor as well as to ensure that your feet can reach the pedals at all times.
