Description

Waist support device with adjustable waist and back supporting effect

Technical Field

The utility model relates to the technical field of lumbar support, in particular to an adjustable lumbar support technical design.

Background

Lumbar support is a device for supporting and protecting the lumbar region, often mounted on a seat, providing lumbar stability and support to the human body, relieving lumbar pressure from sedentary sitting, alleviating lumbar pain, and helping the human body maintain a correct posture. It can help reduce the burden of waist muscle through pressure and closely laminating mode. The conventional lumbar support is often fixedly connected to the frame of the seat to provide lumbar support, however, the shape of each individual varies, and the fixed lumbar support cannot completely adapt to the shape of the lumbar of each individual, thereby providing a flexible support effect.

An adjustable independent lumbar support for seating furniture is disclosed in chinese patent publication No. CN 218571830U, which includes a lumbar support member, a lifting table member, and two side clamping members. The waist support is adjusted back and forth through the lifting table, and the clamping parts on the two sides are used for adjusting the waist support up and down. Therefore, the waist support is adjustable relative to the position of the human body, and the support effect is more flexible.

However, this solution has certain drawbacks: on the one hand, the waist support is used for supporting a human body in a plane, namely only one plane of the back and waist of the human body is supported, and the support is easy to cause angular sense and is not enough in comfort to the human body. On the other hand, although there is an adjustment of the supporting effect of the lumbar support, the adjustment is limited to "position adjustment", that is, the position of the support itself in the front-rear, up-down direction, without adjusting the effect in terms of supporting strength. For people who need lumbar support with higher strength, such as lumbar muscle strain or lumbar degenerative disease patients, the lumbar support device cannot play a role in stably supporting the lumbar region, and cannot limit the position of the lumbar region of the human body so as to help the human body maintain a correct posture.

The auxiliary waist support body is movably arranged at two sides of the main waist support body through the elastic connecting device and is used for clamping the waist of a human body. The elastic connecting device can provide moderate damping and resilience force, when the waist support device is in a free state, the auxiliary waist support body is stressed by the elastic connecting device to clamp the waist of a human body, so that the waist support device can adapt to people with different shapes, and can be tightly attached to the human body curve to support higher parcel. The elastic connection device can be selected from various schemes in the prior art, such as tension springs, torsion springs, tension blocks made of elastic materials, and the like.

The locking device is arranged on the supporting device and used for locking the rotating angle of the auxiliary waist support body relative to the main waist support body. The locking device comprises a locking head which is used for being in conflict with the elastic connecting device, and whether the locking head is in conflict with the elastic connecting device or not is controlled by adjusting the displacement of the locking head, so that whether the auxiliary waist support body is locked or not is controlled. The locking head can be a spring bolt structure in the prior art, and one or more protruding teeth or grooves are matched with the elastic connecting device, so that the auxiliary waist support body is locked. When the human body does not need the parcel support of higher parcel nature, can adjust vice waist and hold in the palm body pivoted angle and lock with the device of locking position after to the suitable position for this kind of waist holds in the palm the device and gets into locking state. Under the locking state, the waist support body only provides the ordinary supporting effect, need not to press from both sides tight parcel and live the waist, realizes the conversion of different waist supporting effects.

This kind of waist support device with adjustable waist back supporting effect through adjusting vice waist support body pivoted angle, can adapt to the people of different shapes, and laminate human body curve and carry out the multidimensional support, improves human travelling comfort.

When the auxiliary waist support bodies on two sides are subjected to external force action to rotate outwards, the limiting strips are arranged at positions corresponding to the outer surfaces of the head blocking shells and are abutted against the main waist support bodies, so that the auxiliary waist support bodies are limited to rotate outwards continuously. The rotary spring can be prevented from being damaged due to the fact that the rotary spring bears force or torque exceeding the bearing capacity of the rotary spring due to overlarge external force. Meanwhile, the position of the limiting strip can be matched with the position of the head blocking shell, so that when the auxiliary waist support bodies at two sides are outwards broken to a specific position by external force, the limiting strip is abutted against the main waist support body, the auxiliary waist support body cannot continue to rotate, at the moment, the position of the head blocking shell just cannot block the locking head, and the locking head is abutted against the rotary spring to realize automatic locking. The position of the limiting strip is matched with the position of the head blocking shell, so that the locking head is easier to collide with the rotary spring to realize automatic locking, and the success rate of the automatic locking of the waist support device is improved.

Preferably, the support device is inclined upward with respect to the horizontal plane gradually in a direction approaching the waist support body.

The support means is inclined upwardly relative to the horizontal plane, giving an upward oblique force to the waist. When a person sits normally on the chair, rather than being perfectly vertical, there is a certain angle of rearward inclination. The design of oblique ascending makes the waist support body higher with the laminating degree of waist, and the ascending force of oblique simultaneously can be more comfortable for human waist.

Preferably, the support device comprises a main frame, a sliding frame connected with the main frame in a sliding way and a telescopic assembly for driving the sliding frame to slide, and the sliding frame is connected with the main waist support body.

The sliding frame is connected with the main waist support body, and the sliding connection of the sliding frame and the main frame is realized through the telescopic component, so that the waist support body is driven to move back and forth, and the position adjustment of the waist support device is realized. The telescopic component can be a pneumatic telescopic device in the prior art, the cylinder of the telescopic component is arranged on the main frame, and the piston rod is connected with the sliding frame, so that the sliding frame is driven to slide relative to the main frame.

Detailed Description

The present utility model will be described in further detail with reference to the accompanying drawings.

The present embodiment is only for explanation of the present utility model and is not to be construed as limiting the present utility model, and modifications to the present embodiment, which may not creatively contribute to the present utility model as required by those skilled in the art after reading the present specification, are all protected by patent laws within the scope of claims of the present utility model.

As shown in fig. 1, the auxiliary waist support body 12 is movably mounted on two sides of the main waist support body 11 through elastic connection devices 13, and is used for clamping the waist of a human body. The supporting device 2 is connected with the main waist support body 11. As shown in fig. 2, the supporting device 2 includes a compression spring 33, one end of which is fixed, and the other end of which abuts against the locking head 31, so as to provide the locking head 31 with an elastic force approaching the elastic force connecting device 13. The locking head 31 is used for abutting against the rotary spring 131 in the elastic device 13 to limit the rotary spring 131 from twisting. The pulling assembly 32 is connected to the capture head 31. When unlocking is needed, the pulling component 32 can be directly pulled to overcome the elastic force of the compression spring 33, and the locking head 31 is driven to be separated from the compression spring 33 for unlocking.

The rotary spring 131 is connected with the auxiliary waist support body 12, and the rotary spring 131 has elasticity and torsionally, so that the auxiliary waist support body 12 is stressed to rotate along the horizontal direction relative to the main waist support body 11, is clamped to the middle, and simultaneously, an external force is applied to the waist support to rotationally adjust the rotation angle of the waist support. The rotary spring 131 is internally provided with a connecting shaft 133 which is connected with the main waist support body 11 and used for limiting the space position of the rotary spring 131, so that the interference locking of the rotary spring 131 by the locking head 31 is easier.

The rotary spring 131 is externally connected with a head blocking shell 132 and is connected with the auxiliary waist support body 12. When the auxiliary waist support body 12 rotates angularly relative to the main waist support body 11, the head blocking shell 132 is driven to rotate together relative to the main waist support body 11. The locking head 31 is positioned on the supporting device 2 and does not rotate relative to the main lumbar support body 11. So when the auxiliary waist support body 12 rotates, the head blocking shell 132 also rotates relative to the locking head 31. When the blocking head 132 rotates to a certain angle, the waist support device forms a free area, so that the blocking head 132 collides with the locking head 31, and the locking head 31 can be prevented from locking the elastic connection device 13 inside the blocking head 132. So that the waist support device can clamp the waist of a human body in a free region without pulling the pulling assembly 32. When the auxiliary waist support body 12 rotates to a certain angle to leave the free zone, the blocking head shell 132 also rotates to a specific position along the axial direction of the auxiliary waist support body, and the blocking head shell does not collide with the locking head 31. The locking head 31 directly collides with the rotary spring 131 under the action of the compression spring 33 to lock, so that the automatic locking function of the waist support device is realized.

The outer surface of the head blocking shell 132 is provided with a limiting strip 134, and the limiting strip 134 is a protruding part, and is provided with a front part and a back part and is used for limiting the angle of the auxiliary waist support body 12 relative to the main waist support body 11 in the horizontal direction. When the auxiliary waist support bodies 12 on two sides are rotated and clamped towards the middle under the stress of the rotary springs 131, the head blocking shell 132 connected with the auxiliary waist support bodies is driven to rotate along the axial position of the head blocking shell 132. The limiting strips 134 arranged at the corresponding positions can collide with the main waist support body 11 to limit the head blocking shell 132 to continuously axially rotate along the main waist support body 11, so that the rotation angle of the auxiliary waist support body 12 is limited to prevent the auxiliary waist support bodies 12 at two sides from collision, and the service life of the device is prolonged.

When the auxiliary waist support bodies 12 at the two sides are rotated outwards under the action of external force, the limiting strips 134 at the corresponding positions are arranged on the outer surface of the head blocking shell 132 and are abutted against the main waist support body 11 so as to limit the auxiliary waist support bodies 12 to continue to rotate outwards. It is possible to prevent the rotary spring 131 from being subjected to a force or torque exceeding its carrying capacity by an excessive external force, causing damage to the rotary spring 131.

Meanwhile, the position of the limiting strip 134 can be matched with the position of the blocking head shell 132, so that when the auxiliary waist support bodies 12 at two sides are outwards broken to a specific position by external force, the limiting strip 134 is in conflict with the main waist support body 11, the auxiliary waist support body 12 cannot continue to rotate, at the moment, the position of the blocking head shell 132 is just in time unable to block the locking head 31, and the locking head 31 is in conflict with the rotary spring 131 to realize automatic locking. The position of the limiting strip 134 is matched with the position of the head blocking shell 132, so that the locking head 31 is easier to collide with the rotary spring 131 to realize automatic locking, and the success rate of the automatic locking of the waist support device is improved.

As shown in fig. 3, the supporting device 2 gradually inclines upwards relative to the horizontal plane along the direction approaching the waist support body 1, so as to exert an upward oblique force on the waist and improve the comfort. As shown in fig. 4, the sliding frame 22 in the supporting device 2 is connected with the main lumbar support body 11, and the sliding connection between the sliding frame 22 and the main frame 21 is realized through the telescopic component 23, so as to drive the lumbar support body 1 to move back and forth, and realize the position adjustment of the lumbar support device. The telescopic assembly 23 is a pneumatic telescopic device in the prior art, a cylinder of which is mounted on the main frame 21, and a piston rod is connected with the sliding frame 22, so as to drive the sliding frame 22 to slide relative to the main frame 21.
