Description

Technical Field

[0001] This utility model relates to the technical field, specifically to a built-in car seat heating element. Background Technology

[0002] Car heating pads are seat cushions that heat car seats, preventing people from feeling cold while driving.

[0003] In the current field of automotive seat heating technology, traditional seat heating pads are usually fixedly installed inside the seat, with their heating area and angle basically fixed. When passengers are sitting, they cannot flexibly adjust the heating position and coverage according to their individual body characteristics, sitting habits, and actual needs. For example, in winter, some passengers want to focus on heating their legs to resist the cold, while others pay more attention to keeping their waist warm. However, existing seat heating pads cannot meet such personalized heating needs. Furthermore, in different scenarios such as long-distance driving and short-distance travel, passengers have different requirements for the heating area and intensity. Fixed heating pads cannot be flexibly switched, resulting in poor applicability and versatility, which greatly affects the passenger's riding comfort. Utility Model Content
