1 results about "Dual effect" patented technology

This application provides a seat foam and a seat. The seat foam includes a foam A-side, which is the side of the foam closest to the occupant. A functional area is disposed on the foam A-side, and the functional area has at least one transition surface, which is a small plane with an angle A greater than or equal to 90 degrees to the foam A-side. A preset area is used to configure a sheet-like occupant sensing device, and the preset area is the orthographic projection area of ​​the sheet-like occupant sensing device on the foam A-side. A stress concentration area is a stress radiation area that overlaps with the functional area and the preset area. A stress relief part is a cut located in the stress concentration area, at the junction of the foam A-side and the transition surface outside the preset area, for stress relief. This solution uses a cut to release stress in the stress concentration area, which not only ensures the flatness of the seat when sitting, but also releases stress protection elements in a timely manner, achieving the dual effect of meeting both seat design requirements and user experience requirements.
