Deep contour back (Fixed and swing away lateral support’s are also available - see page 13) 2 15.3cm (6“) Level of Support The users can choose between 4 different levels of support, depending on their functional needs and level of trunk stability. Shoulder height (Shallow contour / deep contour) Upper thoracic (Shallow contour / deep contour) Mid thoracic (Shallow contour) Lower thoracic (Shallow contour) 5 SIMPLY · EFFECTIVE · SEATING 3 Back Support Height Due to varying user heights, each level of support within the J3 range offers 3 back support heights: Short (S), Medium (M) and Tall (T) Short 4 Medium Tall Backrest Width The J3 back range also comes in a variety of widths that are selected in accordance with trunk width and chair width, ensuring that the back will fit the user as well as their chair.

All prescriptions should be basedxxxxxxxxxxxxxxxxxxxxxxxxxxxx upon the information found during clinical assessment © Sunrise © Sunrise Medical Medical 2008 6 Jay Spine-Align System SIMPLY · EFFECTIVE · SEATING For maximum pressure distribution, correct support and optimal comfort and function, a solid back should reflect an individual’s shape. With this idea in mind, the new J3 spine-align positioning components were designed to allow clinicians and dealers to define, adjust, and refine the shape of the new J3 back in the field. Spine-Align Positioning Components t Provides maximum pressure distribution for skin integrity preservation t Provides optimal support and comfort /sitting tolerance t Infinite number of custom shapes t Multiple evaluation kits To better understand how this system works, let’s take a look at an example of a user with a “C” curve posture*. In this case, a Jay 3 back shallow contour, upper thoracic is attached to the backposts. When the user sits against the back, his support is concentrated in a small area, resulting in peak pressure which may result in compromised skin integrity and discomfort over time. Postural stability is also compromised. (Image on the left side of the picture) medium triangle which will fit in the top and a large triangle fitting in the bottom. This results in a back that matches and supports the user, providing optimal pressure distribution whilst improving stability, comfort and function. Using the angular adjustment capabilities of the new J3 hardware, the backrest angle is realigned to better match the shape of the spine. Once the angle is set, it is easy to add a Spine-align components optimize the J3 back’s ability to support and provide prolonged sitting tolerance. There is an obvious improvement after applying spine-align. * This is merely an example to show the benefits of the Spine-Align System, this in no way should replace clinical assessment.

Additionally, we offer a series of complete spine alignment kits that can be used during the assessment process again and again to ensure optimum user fit, first time. The Spine-Align box contains all the necessary items to adjust the J3 back to each individual’s shape. The box contains over 32 different soft foam components.

The new Jay Mount hardware features a revolutionary hinged clamp design that fits 1.9 cm (3/4”) to 2.8 cm (1 1/8”) tubes. With only one attaching clamp that is compatible with 90% of wheelchairs on the market and no need for additional hardware, the entire ordering and fitting process is simplified. 1.9 cm (3/4”) D Type 2 2.5 cm (1”) 2.8 cm (1 1/8”) To provide multiple hardware mounting locations that in no way altered the required backrest position. Frequently, obstructions such as towel bars and armrest receivers force clinicians, dealers and technicians to make compromises. To maximize compatibility, the unique 2 point attachment J3 back hardware occupies as little space as possible and mounts without affecting the user’s fit. Furthermore unlike other solid backs, the J3 back’s vertical position can be adjusted after the hardware location is set. 9 SIMPLY · EFFECTIVE · SEATING 3 To accommodate individuals who are wide in the hips and narrow in the shoulders using no additional hardware. Many times backs fit the chair but not the user. To address this problem, the team created 5 cm (2”) of built-in width adjustment. For example, a 46 cm (18”) wide chair can now easily accommodate a 41 cm (16”) wide back, which prevents costly re-orders. 41 cm (16”) wide shell 4 41cm (16”) shell adjusted to an 46 cm (18”) wide chair To provide up to 22° of backrest angle adjustability, without reducing seat depth. Jay Mount hardware was designed to minimise loss of seat depth. When the J3 back is reclined the lower back position remains constant, resulting in no loss of seat depth. This is a critical feature for users with postural deformities who may require more extreme angles; Jay Mount hardware prevents compromising their position in the chair. NOTE: Depth adjustability of 5cm or 8.2cm (with extended hardware) is also available independent of angle adjustability Lower seat depth remains constant! 5 Ease of use. With Jay Mount hardware the J3 back can be easily removed and attached with a minimal amount of force and limited dexterity. This empowers users to perform these functions independently. The automatic locking mechanism ensures that the back is securely re-attached first time, every time. www.jay3seating.co.uk This information is for reference only.

Q: I have a user with a trunk width of 33cm (13”) but the hips/seating width is 44cm (17”). I do not see a backrest that will work. What to do? A: Solution: use the next widest backrest and use the shim to narrow. 2. Q: Was the study (Human Anthropometric Measurements) on laterals done with the rehab clients. A: The Anthropometric data was collected from studies conducted on the human conditions of both disabled and able bodied populations. 3. Q: What is the relationship of the position of the deep contour to the user’s torso height? A: The DC laterals are anthropometrically designed to support the rib cage as it relates to the user’s torso height (S, M, L). As the shell gets taller, the majority of the growth is added to the lower portion in order that the lateral is able to support the rib cage on the taller torso. 4. Q: Does the maximum user weight for the J3 back range change between back types and sizes? A : No, all J3 backrests regardless of shape or size have a maximum user weight of 136kg. 5. Q: We know we can fit a 41 cm (16”) back to an 46 cm (18”) chair but can a 56 cm (22”) back fit a 51 cm (20”) chair if mounted forward of the back canes? A: No, the mounting bracket shape does not allow reverse mounting to allow a wider back on a narrow chair. We plan to look into this issue with future projects. 6. Q: Where should the hardware be mounted on the back? A: One of the key advantages of the JayMount hardware is that it can be mounted virtually anywhere. If the customer wants further direction, we recommend mounting it higher on the back tubes or at the midpoint. 7. Q: Is the hardware metric or standard? A: The J3 Back is a pan European product, and therefore we have chosen to use metric tools. We ship with each back the metric tools necessary for assembly. This includes a J3 Back 4mm allen key and a 10mm combo wrench. 8. Q: Can the J3 back be used during transit? A: The J3 back has been fully crash tested and approved to the latest ISO standards, including headrests and accessories. 9. Q: Can the back be used on a power chair with 50 degrees of recline? A: The back can be used on chairs capable of tilt and/or recline, but cannot exceed 60 degrees from vertical in any combination of tilt and/or recline. 10. Q: How can I be sure that a 2 point attachment is as strong as a four point? A: The entire J3 back range including all headrests and accessories, has been extensively tested up to 100,000 cycles with max user load and passed !
