AI Technical Summary
Existing massage chairs cannot effectively avoid the risk of pinching small animals or children when the chair is in a reclining position. The threshold setting of the safety pin release structure is not stable enough and is inconvenient to adjust.
The tilting frame design employs a combination of torsion springs and compression springs. The damping force of the tilting frame is adjusted by adjusting the compression of the compression spring through adjusting bolts, thereby achieving stable release of the safety pin. Combined with buffer springs and limit structures, stability and ease of adjustment are improved.
It achieves stability and ease of adjustment of the safety pin release threshold, ensuring that the massage chair can safely and reliably avoid the risk of pinching under different conditions, with a stable structure and precise adjustment.
