It was reported that the end user was sitting on the seat of the device.The brakes were not engaged.She moved the rollator backwards and the wheels hit an uneven surface.One leg of the rollator broke.The rollator then tipped, causing the end user to fall.She suffered a fractured coccyx.She was treated in the emergency room and discharged with pain medication.The sample was returned and evaluated.The right front leg tubing was fractured above the pin.No voids were noted at the site of the fracture.The frame was bent.No manufacturing defect was identified.The manual states that the brakes must be in the locked position before sitting on the seat.The most likely root cause for this incident is user error.
