Dimensions and Weight Specifications

The document provides detailed measurements and weight data for various chair models, identified by codes such as 4004, EH5004, 470, 2004, and 3004.

Footrest Dimensions (Width x Depth in mm)

• Most models have footrest dimensions of 630 x 680 mm.
• One model has a smaller footrest dimension of 430 x 430 mm.

Seat Cushion Dimensions (Width x Depth in mm)

• Dimensions vary between 440 x 450 mm and 460 x 450 mm.
• Some models specify circular seat cushions with diameters of 400 mm.

Backrest Dimensions (Width x Height in mm)

• Backrest sizes range from 440 x 250 mm to 465 x 870 mm depending on the model.

Total Height (Backrest Upright) in mm

• Heights range from 695 mm to 1410 mm.

Maximum Length of Backrest (Footrest or Horizontal) in mm

• Ranges from 1410 mm to 1630 mm; some models do not specify this dimension.

Maximum Patient Weight

• All models support a maximum patient weight of 150 kg.

Chair Weight (kg)

• Chair weights vary from 37 kg to 107 kg depending on the model.

Adjustment Ranges and Features

Vertical Range (Chair Height)

• Minimum seat cushion height ranges from 460 mm to 530 mm.
• Lift height is consistently 200 mm across models.
• Maximum seat cushion height ranges from 660 mm to 730 mm.

Backrest Adjustment Range

• Backrest can be adjusted from vertical to horizontal positions.
• Some models allow a forward tilt of -5° from vertical.

Chair Rotation

• Most models support chair rotation with snap lock every 90°.
• One model does not support rotation.

Horizontal Seat Movement

• Horizontal seat movement forward and backward is 100 mm for some models; not available for others.

Castors

• Electric castors are available on most models; one model does not have castors.

Electrical Data

• Line power supply: 230 V (3-phase) for all models.
• Nominal frequency: 50/60 Hz.
• Nominal current: maximum 2.5 A.
• Duty cycle for actuators: minimum 6%.

Summary

The document outlines comprehensive technical specifications for a range of chairs, focusing on dimensions, weight capacities, adjustment capabilities, and electrical requirements. Key points include a uniform maximum patient weight of 150 kg, consistent electrical parameters, and variable physical dimensions tailored to different models. Adjustment features such as vertical height range, backrest tilt, rotation, and horizontal seat movement vary by model, providing flexibility for different use cases.
