Key features and benefits

Height-adjustable to accommodate various care scenarios

Height adjustment of shower chairs is crucial for caregiver ergonomics. Our electric linear actuators enable stepless adjustment of the seat height—allowing shower chairs to be raised to the same height as wheelchairs or beds, making transfers between the bed and wheelchairs safe and effortless; and lowering them to a comfortable operating height, effectively reducing the need for caregivers to repeatedly bend over while assisting patients with bathing. Prioritizing ergonomics and eliminating strenuous patient transfers can alleviate the daily workload of caregivers.

Side-lying support and posture adjustment for enhanced bathing convenience

In addition to height adjustment, electric shower chairs also feature electric adjustment for lateral trunk support and leg/arm positioning. Caregivers can adjust the patient to the most comfortable bathing position based on their physical condition and bathing needs—lateral support facilitates back cleaning, while leg and arm adjustments make it easier to wash the lower limbs. An adjustable chair is indispensable for caregivers; otherwise, they would have to exert significant effort assisting patients during their daily work.

Smooth and quiet operation, creating a relaxing bathing atmosphere

Bathing should be a time to relax both body and mind. Our electric actuators maintain extremely low noise levels during operation; the chair's height adjustment and posture changes are silent, ensuring the tranquil atmosphere of the bathroom remains undisturbed. The smooth, seamless motion allows patients to adjust their posture effortlessly, enabling them to enjoy every bath in a state of relaxation.

High protection rating, confidently handles humid environments

Shower chairs are constantly exposed to humid conditions and frequent contact with chemicals such as cleaning agents and shower gel, placing extremely high demands on the equipment's protection rating. Our electric actuators feature a high protection rating, providing full resistance against moisture and chemical intrusion. Constructed from corrosion-resistant materials and featuring a fully sealed design, they ensure stable and reliable performance even in environments with prolonged exposure to water and cleaning agents.

Enhancing patient independence and dignity

The use of electric linear actuators in shower chairs allows users to enjoy greater independence and dignity, thereby enhancing privacy and safety—enabling them to shower in the bathroom without even needing assistance from caregivers. For patients with some level of self-care ability, the autonomous adjustment features of electric shower chairs allow them to complete the bathing process independently, helping them regain a sense of control over their lives and restore their dignity.

Low-power operation, suitable for home power supplies

In home care settings, shower chairs are typically connected to standard household power outlets. Our electric actuators consume power only during the instant of adjustment; power consumption is extremely low in standby mode, so long-term use will not result in a significant increase in electricity bills.

Built-in Hall sensors enable precise control for customers

Our actuators feature built-in Hall sensors that provide real-time feedback on the actuator's travel position and operating status via pulse signals. Based on this data, the customer's control system can precisely monitor real-time seat height and posture, enabling intelligent features such as one-touch reset and position memory.

Richmat's engineers provide end-to-end technical support—from needs assessment and solution design to product delivery—ensuring that our reliable, medical-grade linear drive systems safeguard every moment of bathing hygiene and dignified care.

Other Applications

Patient lifts

Patient lifts (also known as patient transfer devices or patient hoists) are the most essential patient transfer equipment in medical care and rehabilitation. They are widely used in hospital wards, rehabilitation centers, care homes, community care, and home care settings. With the global aging population continuing to grow, the demand for personalized long-term care services is gradually gaining greater attention. Caring for patients with limited mobility is a challenging task, particularly when helping them get up and move around—whether transferring them from the bed to a wheelchair or assisting them in and out of the bath, patient lifts offer significant benefits to both patients and caregivers. In long-term care, patient lifts enhance patients' mobility and comfort while reducing the physical strain and stress on caregivers, enabling patient transfers to be carried out in a safer and more reliable manner.

In our product applications, linear actuators serve as the core drive components for the lifting mechanisms of patient lifts. By receiving commands from the control system or controls, the actuators precisely control the lifting height and speed of the sling or harness—gently raising the patient from a seated position to a suspended state during ascent, and gently lowering them back onto wheelchairs, hospital beds, or shower chairs during descent. The actuator operates smoothly, with controllable movements and extremely low noise levels, while maintaining stable and reliable lifting performance even when bearing the patient's body weight. The actuator is supplied as a component, featuring a built-in Hall sensor, and is designed to be integrated into the customer's control system.

Wheelchairs

Wheelchairs are the most essential mobility aids in the daily lives of people with reduced mobility. They are widely used in medical institutions, care homes, communities, and households. They enhance the independence of people with disabilities in terms of two-point mobility and access to indoor and outdoor spaces, making it easier for them to visit public places such as schools and workplaces, thereby strengthening their sense of connection with society. In the field of assistive technology, wheelchair systems incorporating electric linear actuators have ushered in a new era, bringing users greater convenience and comfort in their daily lives.

In traditional wheelchairs, the seat height, backrest angle, and leg rest position are typically fixed or manually adjustable, making it difficult to meet the needs of users of different body types and diverse usage scenarios. Our electric linear actuator system is a precision drive component specifically designed for multi-dimensional posture adjustment in wheelchairs. By receiving commands from the control system or controls, the actuators precisely control the seat height, backrest recline angle, and leg rest elevation angle, and can even provide standing assistance.
