A safety belt buffering device and a related vehicle safety seat are provided. The safety belt buffering device is applied to a shoulder belt. The safety belt buffering device includes a buffering component, a blocking component and an actuating component. The buffering component includes an accommodating space, and the accommodating space is formed through the buffering component. The blocking component is disposed inside the accommodating space. The actuating component is disposed on the shoulder belt. The shoulder belt movably passes through the accommodating space. The actuating component is driven to move into the accommodating space to contact the blocking component when the shoulder belt is pulled by external impact, and the blocking component is structurally deformed to reduce the external impact. The present invention can obviously decrease the impact energy transmitted from the vehicle safety seat to the passenger, so as to protect safety of the passenger.
