A kind of comfortable headrest that can effectively keep head level
Technical field
The present invention relates to a kind of headrests, are specifically a kind of comfortable headrest that can effectively keep head level.
Background technology
Headrest, as the term suggests referring to the articles for use for fixing and protecting head, generally the headrest described in us is all referring to vapour
Headstock is rested the head on, a kind of driver comfort configuration articles for use and security protection articles for use, and when vehicle knocks into the back, human body can be to due to inertia
After fall, the pressure of vehicle acceleration or deceleration all concentrates on neck and the head of human body fragility at this time, and rests the head on and buffering is then played to this
Human body head is protected in effect.
Most important function of resting the head on is above-mentioned function, and during some coach transportations, passenger doors are often practised
Inertia enters sleep state, because prolonged automobile journey can make one tired, and is sitting at this time on seat, head leans against head
It is often unique rest function on pillow, but running car is unavoidable to jolt, and existing headrest inclines on head in order to prevent
The structure of both sides protrusion is tiltedly often designed as, but effect is very undesirable, therefore passenger departs from head because automobile rocks head
It is also what is be frequently seen that pillow is waken up with a start suddenly, can so make passenger very uncomfortable, therefore can be improved for this.
