The invention discloses a translational energy-absorbing seat for protecting the neck during rear-end collision and belongs to the technical field of automotive passive safety. A seat translational energy-absorbing mechanism is arranged on a slideway of a conventional automobile seat; and the mechanism is arranged under a seat cushion and symmetrically arranged on two sides of the seat. During rear-end collision, the provided translational energy-absorbing mechanism can make the seat and the passenger translate a certain distance backward under the action of a certain constraint force, and reduce relative motion of the trunk and the head of the passenger. Therefore, the neck injury to the automobile passenger during rear-end collision is effectively reduced. Meanwhile, the translational energy-absorbing seat overcomes the defect that the conventional passenger neck protecting seat during rear-end collision has heavy weight, high cost, narrow rear-end collision speed range, and the like, and has better application prospects.

The apparatus includes a helmet, a body harness and a plurality of anchor assemblies connecting the helmet to the body harness. The anchor assemblies are adjustable to limit the cervical rotation, lateral bending, flexion and extension ranges of motion of a wearer to a predetermined set point, each anchor assembly including a plurality of guide cords extending from the helmet to an anchor of the anchor assembly, the plurality of guide cords being attached to, but individually adjustable with respect to, the anchor.

An active headrest apparatus for a vehicle seat. A contact area in which the upper body of a person who is seated in a car in the event of a rear-end collision of the car is moved backward due to an inertial force and contacts a back plate can be increased, and a distance at which a headrest is moved and rises can be increased so that the function of an active headrest can be more faithfully performed and neck injury of the person who is seated in the car can be prevented to the maximum.

A device for treating neck tension or neck injury is provided. The device includes a base connected to a head support which is capable of continuous bi-directional movement relative to at least one axis of said base. The device is configured such that the continuous bi-directional movement is capable of repetitively flexuring and/or extending neck vertebrae of a user of the device.

A helmet is wearable on a user's head for mitigating neck injury. The helmet incorporates an outer member which defines a concavity; an inner member, at least a portion of which is located within the concavity; and a path-motion guide mechanism which couples the inner member to the outer member. The path-motion guide mechanism permits guided relative movement between the inner member and the outermember in response to an impact force. The guided relative movement is constrained to one or more predetermined paths and comprises, for each of the one or more predetermined paths, relative translation and/or rotation between the inner and outer members.

An apparatus for preventing neck injury for use in a vehicle seat, which is connected between a recliner base installed on a back frame and a plate base on which a seat cushion is provided, may include a front connection link that is hinged to a front part of the recliner base at an upper end thereof and to a front part of the plate base at a lower end thereof; and a rear connection link that is hinged to a rear part of the recliner base at an upper end thereof and to a rear part of the plate base at a lower end thereof, wherein the front connection link is pivoted at a greater angle than the rear connection link such that the back frame moves in a forward direction in the event of a vehicle rear-end collision.

The invention relates to the technical field of passive safety devices, in particular to a top-mounted gasbag. The gasbag comprises a gasbag body, a gas generator and a shell, wherein the upper middlepart of the gasbag body is provided with a separable part, the separable part divides the gasbag body into an upper gasbag cavity and a lower gasbag cavity, the two sides of the separable part are provided with gas guide parts, and the upper gasbag cavity and the lower gasbag cavity are communicated by the gas guide parts. Compared with the prior art, the gasbag has the advantages that a top-mounted gasbag structure is designed, the separable part is arranged at the upper middle part of the gasbag body, and when a driver moves towards the gasbag filled with gas and squeezes the gasbag, the portion, close to the head of the driver, of the gasbag is compressed more easily, so that the risk of neck injuries caused by excessive backward bending of the neck of the driver is reduced; moreover,the gasbag adopts a simple design for cutting and sewing pieces and is simple in structure, low in cost and easy to popularize.

The invention discloses an automatic piano music score page-turning device, and belongs to the technical field of musical instrument auxiliary equipment. The automatic piano music score page-turning device comprises an adjusting mechanism, a supporting plate, a page dividing mechanism and a page-turning mechanism. The supporting plate is arranged at the upper end of the adjusting mechanism, a supporting assembly is arranged at the lower end of the supporting plate, the adjusting mechanism comprises a height adjusting assembly and an angle adjusting assembly, and the angle adjusting assembly isarranged at the upper end of the height adjusting assembly. The page dividing mechanism comprises a compression assembly and a page dividing assembly, the page dividing assembly is connected with thesupporting plate through the compression assembly. The page-turning mechanism comprises a shell, a shell cover, a page-turning assembly and a turning-back assembly, the shell is arranged at the upperend of the supporting plate, and the shell cover is located at the front end of the shell. The automatic piano music score page-turning device can realize automatic page turning and can turn a page back which is turned early or redundantly, a user can adjust the height and angle according to own height, the automatic piano music score page-turning device is suitable for different groups of peopleand puberty people in the period of rapid growth, and neck injuries of the user are avoided.

A harness providing neck support for weightlifters, to reduce the risk of neck injuries, resulting from improper lifting form. The harness includes a soft foam support collar worn around the neck. Furthermore, it includes a strap, ring, loop, and fastener system to secure the harness to a weightlifter's pre-existing lifting belt. The harness provides downward tension for support, ease of removal between uses, and enables the wearer to adjust for a comfortable fit. The harness stabilizes the neck, while allowing full range of motion of the arms, shoulders, and chest. This invention is unique in that it provides neck support specifically for weightlifting, and attaches to a waist-level supportive device.

A specialized harness supports the weight of a violin or a viola, eliminating the need for the player to engage the neck or chin to support the instrument while playing. The harness transfers the weight of the instrument to larger muscles in the player's back or shoulder, thus providing ergonomic assistance to the player, and encouraging beneficial posture while playing. Such an ergonomic apparatus may be further equipped with a counterweight. Use of the violin harness permits playing freely, without a need for customary accessories. The violin harness may allow those with upper torso or neck injuries, who might otherwise be prevented from playing the violin, to do so comfortably and painlessly.

The invention discloses a child car seat. A head rest is pivotally connected with the backrest through a rotating shaft, and the head rest can rotate forward and backward about the rotating shaft. Thechild car seat also includes a head rest resetting protection device which plays a damping and/or limiting role on the rearward movement of the head rest main body when the head rest is rotated backward and resettled. By pivotally connecting the head rest to the backrest, when the impact occurs, the head rest is always protected on the outer periphery of the head and neck of the child, and a headrest resetting protection device is added. In the process of head rebound after the impact, the head rest resetting protection device is forced to compress and absorb the head energy, which can effectively counteract the impact force on the head and neck of the child, prevent the neck injury of the child, and greatly improve the safety of the child in the car.
