Description

Technical Field

[0001] This utility model relates to the field of subway priority seating, specifically an adjustable priority seating for subway use. Background Technology

[0002] As a vital component of urban public transportation, the subway carries a large number of passengers daily. Among these, priority seating, specifically designed for the elderly, children, the sick, the disabled, and pregnant women, is a significant embodiment of the subway's humanistic care. However, most priority seating currently available on the market is of a fixed structure, and its reclining angle cannot be adjusted to suit the actual needs of passengers.

[0003] For pregnant women, their bodies undergo significant changes at different stages of pregnancy, and their requirements for seat comfort also vary. In early pregnancy, pregnant women may need a more upright sitting posture to maintain stability. In mid-to-late pregnancy, as the abdomen gradually protrudes, pregnant women need to adjust the seat angle to reduce pressure on the lower back and abdomen and relieve fatigue. However, existing fixed-angle priority seats cannot meet the personalized needs of pregnant women at different stages of pregnancy, which can easily lead to discomfort for pregnant women. In fact, prolonged uncomfortable sitting may even affect the health of the pregnant woman and the fetus. In addition, priority seats without angle adjustment function cannot provide suitable support for other passengers with physical disabilities who need to lean against and rest. Therefore, it is necessary to design an adjustable priority seat for subway use to solve the above problems. Utility Model Content
