The invention relates to a diffuser for an airbag and a passenger airbag. The diffuser for the safety air bag comprises a diffuser bag located in an air bag body of the safety air bag, and an inlet of the diffuser bag is fixed to an inflation inlet of the air bag body and communicated with the inflation inlet of the air bag body; the blocking part is located in the diffuser bag, the blocking part is fixedly connected with a cloth piece opposite to the diffuser bag so as to block gas from penetrating through, and a bent and forked gas inlet channel is formed by the outer wall of the blocking part and the inner wall of the diffuser bag. A bent and forked air inlet channel is formed through the blocking part in the diffuser bag, so that the airflow speed of air generated by the air generator is reduced, the pressure intensity in the safety air bag in the first 10 milliseconds is reduced, the unfolding process of the safety air bag becomes mild, and the safety performance of the safety air bag is improved. Therefore, the completeness of the safety air bag and the completeness of a windshield, an instrument panel and an instrument panel around the safety air bag are guaranteed, and application of materials with more cost advantages is facilitated.
本公开涉及一种用于安全气囊的扩散器及乘客安全气囊。用于安全气囊的扩散器包括:扩散器袋,位于安全气囊的气袋主体的内部,所述扩散器袋的入口固定在所述气袋主体的充气口处,并与所述气袋主体的充气口连通;阻挡部,位于所述扩散器袋内,其中,所述阻挡部与所述扩散器袋相对的布片固定连接以阻挡气体穿过,所述阻挡部的外壁与所述扩散器袋的内壁形成弯曲且分叉的进气通道。通过扩散器袋内的阻挡部,形成弯曲且分叉的进气通道,从而降低气体发生器产生的气体的气流速度,减小前10毫秒安全气囊内的压强,使安全气袋的展开过程变缓和,从而保证安全气囊的完整性以及安全气囊周围的挡风玻璃、仪表板和仪表盘的完整性,利于更有成本优势的材料应用。
