Magnetic field-based massage device for vehicle seats and vehicle seats having magnetic field-based massage devices

[0001] The present invention relates to a magnetic-based massage device for a vehicle seat and a vehicle seat having a magnetic-based massage device, and more particularly, to a magnetic-based massage device for a vehicle seat and a vehicle seat having a magnetic-based massage device, which is configured to be relatively compact compared to a mechanical massage device and thus can be efficiently applied to a vehicle seat, while also improving the degree of freedom in designing a vehicle seat, and which can reduce fatigue and prevent drowsy driving during long-term driving through a physical massage effect and various operating modes using a magnetic field.

[0002] Massage is a medical auxiliary therapy that regulates the body's tone, helps blood circulation, and relieves fatigue by applying various forms of mechanical stimulation to parts of the body, such as kneading, pressing, pulling, tapping, or moving the body.

[0003] The growing demand for massage has led to a surge in demand for massage devices or appliances that offer artificial massage functions, driven by economic and time constraints. In other words, as demand grows for massage to relieve fatigue and stress by loosening tense muscles, a variety of time- and cost-effective massage devices are being released.

[0004] For example, a device is being developed that can provide massage to a user by incorporating a module for providing massage into a vehicle seat, such as a car seat.

[0005] Fig. 1 is a perspective view showing a conventional pneumatic vehicle massage chair, in which, as shown, a plurality of air cells (3) are installed on a base plate (2) arranged inside a seat (1). A space is formed inside each of these air cells (3) so that air can be injected therein.

[0006] These conventional vehicle massage chairs have air cells (3) made of soft materials, which gradually weaken their durability due to repeated contraction and expansion. In particular, when the massage chair is applied to a vehicle interior, the temperature inside the vehicle becomes high during seasons or regions with high outside temperatures, causing deformation of the air cells (3).

[0007] Therefore, the soft air cell (3) exposed to the high temperature inside the car cannot make contact with the uneven pad surface (not shown) when a passenger sits and is subjected to repeated loads, and slipping occurs in the relatively thin pad surface portion, and the slipped air cell (3) bends due to the applied load and is ultimately damaged, thereby preventing the massage system from achieving its original performance.

[0008] Meanwhile, in the case of the mechanical massage module including a roller or ball-shaped sampler proposed in Korean Patent Publication No. 10-2533638, there is a problem that it is not suitable for application to a vehicle seat due to its relatively complex configuration and large volume.

[0009] Therefore, there is a need for the development of a vehicle massage device that can be applied to vehicle seats and provide efficient massage.

[0010] Accordingly, the present invention, which aims to solve the above-mentioned conventional problems, provides a magnetic field-based massage device for a vehicle seat and a vehicle seat having a magnetic field-based massage device, which can be configured relatively compactly compared to known mechanical massage devices by providing a massage effect using a magnetic field, and thus can be efficiently applied to a vehicle seat and improve the degree of freedom in designing the vehicle seat.

[0011] In addition, the present invention has another purpose of providing a magnetic field-based massage device for a vehicle seat and a vehicle seat having a magnetic field-based massage device that can massage the entire back including the cervical region through various operation modes such as a driving mode as well as a stationary mode, thereby reducing fatigue and preventing drowsy driving during long-term driving.

[0012] In addition, the present invention provides a massage function using a magnetic field, and also has a cooling / heating function, so that there is no need to configure a separate cooling / heating function unit in the vehicle seat, and it is configured relatively compactly compared to a mechanical massage device, so that it can be efficiently applied to the vehicle seat, and another purpose is to provide a magnetic field-based massage device for a vehicle seat and a vehicle seat having a magnetic field-based massage device that can improve the degree of freedom in designing the vehicle seat.

[0013] In addition, another purpose of the present invention is to provide a magnetic field-based massage device for a vehicle seat and a vehicle seat having a magnetic field-based massage device that can massage the entire back, including the cervical spine, through various operating modes, such as a driving mode as well as a stationary mode, thereby reducing fatigue and preventing drowsy driving during long-term driving.

To this end, the magnetic field-based massage device for a vehicle seat according to the present invention may further include a magnetic field generating unit driving device (500) that allows the magnetic field generating unit (100) to be driven up and down inside the seat.

[0073] The magnetic field generating unit driving device (500) includes a driving rail (510) provided on the inside of a vehicle seat, a driving guide plate (520) provided on the back (inner surface) of the vehicle seat, a driving driving unit (530) provided on one side of a device base plate (10) and configured to generate a driving force to move along the driving rail (510), a driven driving unit (540) provided on the other side of the device base plate (10) and configured to drive along the driving rail (510) by the driving force of the driving driving unit (530), and a plurality of rolling rollers (550) formed on the upper surface of a magnetic field coil receiving housing (110) of the magnetic field generating unit (100) and rotating while contacting the driving guide plate (520).

[0076] The rack gear (512) is provided on the inner side of the lower surface of the guide frame (511) and meshes with the drive gear (535) of the drive driving unit (530) to be described below. At this time, the rack gear (512) is formed on the edge side of an extension plate that extends with a predetermined width from the inner side of the guide frame (511). In other words, the extension plate extends with a predetermined width, and is formed as a flat portion on the proximal end portion side based on the width direction, and is formed as a rack gear portion on the distal end portion side.

[0077] In addition, a limit switch (513) is provided at one end and the other end of the driving rail (510), and a projection formed on the device base plate (10) comes into contact with the device at the point where movement toward the upper or lower side is completed, thereby limiting further movement.

[0079] Specifically, the driving guide plate (520) is formed as a plate that is in close contact with the back surface of the vehicle seat, and is preferably formed as a plate made of stainless steel.

[0080] Here, the driving guide plate (520) may be formed with an opening (521) in the center so that the magnetic field generated from the magnetic field generating unit (100) can be smoothly transmitted to the front side (human body side).

[0081] Additionally, the driving guide plate (520) may be formed with a driving guide slot (roller guide slot) (522) formed through which the back of the seat is exposed so that the cloud roller (550), which will be described in detail below, can be guided and physically massage the back of the human body. This will be described in detail in the description of the cloud roller (550) below.

[0082] Continuing, the driving driving unit (530) is a component provided on one side of the device base plate (10) and configured to generate driving force to move along the driving rail (510).

[0084] The support bracket (532) is equipped with a bearing, and the drive shaft (533) is rotatably supported by the bearing.

[0085] The above driving force transmission means may be configured as a gear train or gear module. For example, the driving force transmission means may be configured to include a first gear provided at the end of the rotational shaft of the driving motor (531), and a second gear provided on the driving shaft (533) and meshed with the first gear.

[0086] Continuing, the driven driving unit (540) is provided on the other side of the device base plate (10) and is a component configured to drive along the driving rail (510) by the driving force of the driving driving unit (530).

[0087] Specifically, the driven driving unit (540) includes a plurality of roller support brackets (541) provided at intervals on both sides of the upper surface of the other end of the device base plate (10), and a driven roller member (543) having a rotational shaft (542) rotatably coupled to the roller support bracket (541) and guided (i.e., driven) along a guide frame (511) of a driving rail (510).

In the drawing, the stopper (544) is shown as being provided on one side of the device base plate (10), but may be provided on both sides of the device base plate (10). As mentioned above, when the limit switch (513) is provided, the stopper (544) may be omitted.

[0089] Continuing, a plurality of cloud rollers (550) are formed on the upper surface of the magnetic field coil receiving housing (110) of the magnetic field generating unit (100) and are components that rotate in a cloud manner while contacting the driving guide plate (520).

[0090] The present invention can be configured to physically pressurize and massage the back of a passenger in contact with a vehicle seat by a plurality of cloud rollers (550).

[0091] In other words, as shown in FIGS. 10 and 11, the plurality of cloud rollers (550) can be configured so that the edge portions contact the driving guide plate (520) to roll, and the central portions are exposed to the back side of the sheet through the driving guide slot (522) formed in the driving guide plate (520) to apply pressure.

[0092] Specifically, the cloud roller (550) is formed in a cylindrical shape and includes a roller portion (551) that rotates in a cloud by contacting the back surface of a driving guide plate (520) having a driving guide slot (522) formed at the edge thereof, and a massage protrusion (552) that is formed in the central portion of the circumferential direction of the roller portion (551) and contacts the back surface of the front of the seat through a driving guide slot (522) formed in the longitudinal direction of the driving guide plate (520) to a predetermined length (movement distance).

[0093] The massage protrusion (552) may be formed by protruding across the entire circumferential surface of the roller portion (551), or may be formed by protrusions having the same degree of protrusion and / or different degrees of protrusion at intervals in the circumferential direction, and may be formed in a tooth shape.

[0094] As described above, since the magnetic field coil receiving housing (110) is provided with a cloud roller (550) on the upper surface, it can travel smoothly while contacting the back surface of the driving guide plate (520), and it is possible to perform a magnetic field massage in a state as close as possible to the human body when moving up and down.

[0095] In addition, when the cloud roller (550) is configured with a massage protrusion (552), the massage protrusion (552) not only provides a massage function, but also moves while being guided along the driving guide slot (522), thereby ensuring stable driving performance of the device.

[0096] Meanwhile, the magnetic field generating driving device (500) may further include an elastic support unit (560) provided between the device base plate (10) and the magnetic field generating unit (100) to elastically support the magnetic field generating unit (100) so as to freely move up and down with respect to the device base plate (10).

[0097] The elastic support unit (560) includes a vertically movable rod (561) whose one end is fixed to each of the four corners of the magnetic field coil receiving housing (110) and whose other end penetrates the device base plate (10) and extends toward the lower side of the base plate (10), a movement limiting member (562) provided at the other end of the vertically movable rod (561), and an elastic member (563) provided between the upper surface of the device base plate (10) and the lower surface of the magnetic field coil receiving housing (110) to elastically support the magnetic field coil receiving housing (110).

[0098] The movement restriction member (562) may be composed of a single plate member to which the other end of each of the upper and lower movement rods (561) is connected.

[0099] The elastic member (563) may be configured in the form of a coil spring that is provided to surround the vertically moving rod (561).

[0100] Meanwhile, when the present invention further includes the magnetic field generating driving device unit (500), the control unit (400) may further include a movement position selection operation unit (440) that inputs a manual operation input command to control the movement position by forward or reverse rotation of the driving motor (531), and an automatic drive selection operation unit (450) that causes the driving motor (531) to automatically operate according to a set program.

[0101] FIG. 13 is an exploded view showing a magnetic field-based massage device for a vehicle seat according to another embodiment of the present invention, which is mostly the same as the magnetic field-based massage device for a vehicle seat according to an embodiment of the present invention illustrated in FIG. 8, and differs in that it further includes a fan-integrated thermoelectric element module (250).

[0102] That is, according to another embodiment of the present invention, the heat dissipation unit (200) may further include a fan-integrated thermoelectric module (250) that generates cold air (heat absorption) on one side and generates warm air (heat generation) on the other side by the Peltier effect on the lower side of the heat dissipation fan (240). In this case, regardless of whether the massage function is used, a cooling function (cold air sheet function) and a heating function (heat sheet function) can be provided depending on the direction of the current.

[0103] The heat dissipation unit (200) including the above-described fan-integrated thermoelectric module dissipates heat caused by the generation of a magnetic field in a massage mode that generates a magnetic field and provides a massage. The dissipated warm air can provide a heating function to the vehicle seat. At this time, the operation of the thermoelectric module (250) is stopped.

[0104] In addition, when providing a cooling function to a vehicle seat, such as in the summer, the thermoelectric module (250) is operated so that cold air (cold wind) from the inside is blown by the heat dissipation fan (240). At this time, the operation of the thermoelectric module (250) can provide cold air while cooling the heat generated by the magnetic field in the massage mode, and when the massage mode is not used (i.e., when the operation of the magnetic field generating unit (100) is not operated), only cold air is blown, thereby providing a cooling function to the vehicle seat.

[0105] Of course, when the massage mode is not used, that is, the operation of the thermoelectric element module (250) is not performed, and only the heat dissipation fan (240) is operated so that the ventilation function by the heat dissipation fan (240) is provided.

[0106] According to another embodiment of the present invention, the operation of the thermoelectric element module (250) can be automatically performed based on a detection signal from a temperature sensor (not shown) provided on one side of the inside of the vehicle seat. In other words, when the temperature is higher than the set temperature due to the heat generated by the magnetic field in the magnetic field generating unit (100), the temperature sensor detects this and the operation of the thermoelectric element module (250) can be performed.

[0107]

[0108] According to the magnetic field-based massage device for a vehicle seat and the vehicle seat having the magnetic field-based massage device according to the present invention as described above, since it is implemented in a massage method using a magnetic field, it can be configured relatively compactly compared to a known mechanical massage device, so that it can be efficiently applied to a vehicle seat, the degree of freedom in design of the vehicle seat can be improved, and a sufficient stimulation distance can be secured for the back of the human body having a curved part, and massage can be performed through various execution modes, so that the massage effect can be maximized.

[0109] In addition, the present invention has the advantage of being able to provide concentrated massage to the user's desired area, including the cervical region, thereby reducing fatigue and preventing drowsy driving during long-term driving, and effectively absorbing electromagnetic waves while maintaining a close distance from the human body, thereby eliminating concerns about electromagnetic wave hazards.

[0110] The embodiments described in this specification and the attached drawings are merely illustrative of some of the technical concepts encompassed by the present invention. Therefore, the embodiments disclosed in this specification are intended to illustrate, rather than limit, the technical concepts of the present invention. Therefore, it is self-evident that the scope of the technical concepts of the present invention is not limited by these embodiments. All modifications and specific embodiments that can be easily inferred by those skilled in the art within the scope of the technical concepts contained in the specification and drawings of the present invention should be construed as being included within the scope of the rights of the present invention.
