Krabat Sheriff

In short

Krabat Sheriff S1 and S2 are active children’s wheelchairs designed by Krabat. The wheelchairs are for indoor and outdoor use, and is highly adaptable with numerous adjustment options.

The child sits on a saddle seat, which separates the legs from each other. The abducted hip position provides an open angle of the hips which tilts the pelvis forward into a neutral position. This, together with the widespread position of the feet, creates a large base of support. The result is a very stable position that reduces the need for upper body support.

Krabat Sheriff S1/S2 has a compact and modern design that invites participation. The smart design draws attention to the child and not the chair. The wheelchair allows more freedom of movement and variation.

 

Read on

Sheriff S1/S2 is a light weight indoor / outdoor wheelchair with slightly cambered propelling wheels. It has great precision and is very maneuverable. Sheriff S1/S2 is also suitable for children with impaired arm function. A compensation mechanism is available (optional) that makes it possible to maneuver the wheelchair with one hand only. This mechanism makes it easier for the child to steer straight ahead and adds minimal extra weight to the chair.  This patented solution is unique and is made only by Krabat AS.

The brake handle is assembled right at the front of the saddle to make it more accessible to users and assistants alike. The brake handle locks both wheels and can be operated with one hand only. Little strength is needed to turn the brake on and off.

The seat is designed to support the pelvis is in a neutral and stable position which in turn allows the spine to maintain its natural curvature. The seat and back of the chair can accommodate a SWASH orthosis for children who require this. The upholstery is durable and machine washable. Stains can be easily  removed with a cloth.

Krabat Sheriff S1/S2 is suitable for children with a variety of diagnoses, and it is highly adaptable. The angle of the seat, the height of the seat and backrest, the width of the propelling wheels, and height and position of the footrests can easily be adjusted to find the optimum sitting position. All angles and positions can be set infinitely. The Krabat Sheriff S1 is available with  20” propelling wheels and the S2 is available with 24” propelling wheels.  A hip belt and footrests with straps are included as standard equipment. A push bar, tipping protection, splash guards, spoke guards and a variety of different waistcoats and support straps are optional. For children in need of extra upper body support, the Sheriff S1/S2 can be delivered with the Plus backrest and optional Plus equipment.

To fully benefit from the wheelchair, the child should have some truncal stability, however an independent sitting function is not necessary.

Anatomical benefits

Krabat Sheriff S1/S2 provides the child with a balanced and safe sitting position with dynamic postural control which enables the child to move freely at all levels.

The sitting position gives optimal joint stability and comfort. The two articular surfaces in the hip joint have maximum contact in the sitting position.

The sitting position can prevent complications such as muscle contractures, hip pain and sublucations may be prevented.

All major joints in the lower extremities become centered, which promotes normal muscle tone and muscle length. This is particularly important for the adductors, which are often tight in children with spasticity.

The spine can work actively in its natural curvature. The saddle seat can be adjusted to allow the pelvis to be placed/tilted in the correct position, giving the child’s spine optimum working conditions.

The saddle seat enhance an aktive sitting position rather than a passive.
