Description

seat adjustment system

technical field

The invention relates to seat support adjustment technology, in particular to a technology for actively adjusting the sitting posture and riding comfort of an occupant.

Background technique

Generally speaking, the supporting surface of the seat in contact with the user includes the top surface of the seat cushion, the front of the seat back cushion, etc. for the user to sit on. In order to make the curvature and width according to the user's preference To adjust, the existing seat embeds a plurality of air bags in the seat support surface, and is provided with an inflation and exhaust control device that can be operated by the occupant to adjust the deflating state of each air bag. When the exhaust control device is used to adjust the inflation and exhaust state of each airbag, the curvature and amplitude of the support surface will change, so that the contact mode between the support surface and the occupant will change, and the occupant can rely on their own Use touch to adjust the support effect of the support surface, for example: adjust the contact method between the top surface of the cushion and the thigh of the human body, the contact method between the back cushion and the back and lower back of the human body, etc.

Alternatively, these airbags can be dynamically changed by inflation and exhaust through the inflation and exhaust control device, so that the support surface will provide the occupant with a dynamic support effect like a massage.

Because different passengers have different habitual sitting postures and subjective tactile sensations, the support effect adjusted in this way is not necessarily the best support effect in terms of human health care or medicine. For example: users In the first few minutes of sitting on the seat, the support surface of the seat may be adjusted to the most comfortable state subjectively. Excessive pressure is concentrated on a certain supporting state, which will cause poor blood circulation or excessive force in local muscles. Once you ride for a long time, you will feel uncomfortable or sore, and you will not be able to sit still.

When this uncomfortable feeling occurs, the user can only adjust the support state of the support surface according to the current tactile sensation. Since the uncomfortable feeling has already occurred at this time, the user often over- Adjust the support pattern of the support surface, and after riding for a period of time, other parts will feel uncomfortable again.

In the existing technology, some existing seats are specially provided with a plurality of pressure detectors corresponding to each air bag, and a memory device for recording the pressure state in each air bag. The user takes great pains to find the best support state and record it, so that the same user can quickly make the seat present the same support effect when riding next time.

However, as mentioned above, this kind of support effect based on subjective touch and empirical rules is often not suitable for long-term riding of the human body, and may even cause the occupant to sit in an improper sitting posture for a long time, causing chronic harmful effects, such as Health problems caused by poor blood circulation and poor sitting posture.

In view of this, the inventor has developed a seat adjustment method and system to provide an active adjustment technology that is completely different from the aforementioned passive adjustment technology, so that the occupant can obtain a more comfortable ride.
